2009 XM-3500 A Bit DIfferent

I got to help a friend unwrap and look-over his new 2009 XM-3500 last week. There are a few differences from the 2008 bikes - in a good way!

Delivery

The bike was delivered by Overnight – a contractor for UPS freight. This truck wasn’t equipped with a lift-gate - we used a saw horse and a counter top to make a ramp. One pushing, one pulling, and the package slid to ground level. (Note: lift-gate service should have been provided – it’s the primary reason for the $50 home delivery charge. When UPS calls to set-up a delivery appointment, remind them that you’ve paid for a lift-gate delivery. It’s easier on the hands and back, and is quicker than taking the top off the workbench…)

landed_320.jpgtwisted_320.jpg

The wooden spacer under the metal frame (it’s not really a pallet, just a set of legs to make room for a fork lift or pallet jack) was damaged, and the steel frame was bent.

The wheels appear to have been deflated, pushed into the steel frame, and then inflated so that the tires wedged into the tubes provided on the frame. One could use a pair of channel-lock pliers to rip the tubes away from the frame like we did, but deflating the tires would be much easier. Too bad we didn’t think of that until the bike was freed from the frame…

There was absolutely no shipping damage on the bike. No scratches, no cracks, nothing injured at all. All fasteners were in place and appeared to be properly tightened. After four days and 22 KM on the road there is no need for a repair ticket.

Some details and observations

This bike was manufactured on Nov 15, 2008 and is a 2009 model per the VIN. The VIN is 5XWMLE0569Nxxxxxx The VIN is located on a plate on the right side swing arm for the rear wheel. It is also stamped into the frame under the seat on the right side (as riding). There is a small snap-in panel in the underseat bin to access the VIN.

The Thundersky cells in the pack are all properly badged, with the badge oriented correctly, and have proper serial number barcodes.

The tail/brake light unit has been replaced by a pair of lights with two dual-filament bulbs. Tail lights are bright – brake lights are blinding. The tail light sockets have properly crimped terminals.

front_320.jpgLS_320.jpgrear_320.jpgrs_320.jpg

The mechanical ‘ABS’ module is in place on the front brake caliper, but is not installed on the rear.

Both brake calipers are installed on brackets and appear to be installed as designed. The front caliper places the brake pads over the rotor. The rear brake is still rotated a bit so that the lower portion of the brake pads are out of position. (link to rear brake mod)

Wiring connections in the harness are made with waterproof, locking connectors. There are no signs of twisted wires or electrical tape on any connections or fixtures accessible on the body.

The circuit breaker is not mounted inside the storage bin – its attached to the side of the bin ‘inside’ the bike. It’s accessible thru a hole in the wall of the storage bin.

circuit_breaker_320.jpgunder_seat_bin_320.jpgcharger_under_seat_320.jpg

The headlight is not ‘always on’. There is a three-position switch near the right handgrip with off/parking/on for headlights. The left grip has the high/low beam switch. I would guess the headlights to be the 18W lamps others have seen on their 3500s. The headlights and center ‘parking’ light are excellent for visibility from the front. Headlight coverage and range is probably adequate for city/suburban areas with street lights.

ls_grip_320.jpgrs_grip_power_320.jpg

The speedometer is lighted from the top. It does an adequate job of illuminating the upper ½ of the speed display, but the bottom ½ is fairly dark.

There are two horn buttons, one on each side. The unmarked rocker-switch under the right-side switch cluster is the ‘low-speed/high-speed’ switch.

The speedometer appears to be indicating faster than actual but is fairly accurate. GPS runs at three speeds gives the following:

Indicated GPS Error (actual speed is ___ from speedo display) KPH MPH MPH MPH 20 12.4 9 3.4 lower 40 24.8 22 2.4 lower 60 37.2 32 5.2 lower

Best speed so far was 80 KPH indicated. On different speed runs, I saw 39-43 MPH, but the radar-operated ‘school zone’ speed sign was after a curve and didn’t pick me up until I was fairly close to the sign, so there wasn’t a lot of time for the speed to stabilize. I didn’t feel comfortable riding someone else’s bike at full speed with a GPS in one hand…

This bike has the easiest center stand I’ve ever used. The 125, 250, and 650 road bikes I’ve owned had a small ‘stub’ to step on near the bottom of the center-stand’s foot. You basically ‘stand on’ the stub to keep the stand from moving while simultaneously lifting the bike upward and backward with one hand. This center stand has a long arm that curves up from the center-stand’s foot. Pressing down on the end of the arm lifts the bike up and onto the stand – no upper body strength required! The first time I put the 3500 on the stand I thought I was going to launch it into the garage ceiling…

The bike shipped with a 60V10A Thundersky charger that is “suitable for 20 cells.” The output of the charger feeds a pack positive and a pack negative connection. Charge voltage is good for 19 cells - the charger appears to be ‘tuned’ to not overcharge a slightly-out of balance pack. All 20 cells appear to be fairly close in voltage after a top-off charge. Voltages ranged between 3.335 and 3.354. There is no BMS on the bike. The charger socket is under the seat on the forward wall of the storage bin.

The tool kit included contains a 10mm nut driver, a 12mm/14mm open-end wrench, a small combination straight/Phillips screwdriver, two Allen wrenches. Also in the tool kit are the four screws that hold the rear swing-arm covers. The tool kit is in a small vinyl zip bag most commonly used by kids to hold pencils.

The manual is of decent quality and in English. It has a schematic and pictorial wiring diagram, but I can’t vouch for its accuracy. A couple of pictures appear to be from earlier models (as does some of the text). The photo of the battery pack shows lead-acid batteries. Overall, it’s certainly not from Honda or Suzuki, it’s much better than I expected.

It doesn’t take much time to access the battery pack. There’s a small door ahead of the seat that gives access to the most forward 4 cells. The under-seat storage bin comes out with four bolts and two screws. That gives access to the entire pack, the circuit breaker, the charging plug, and controller wiring. It’s also possible to replace the tail light bulbs from here, but it will take small hands.

The body panels fit well. Gaps were small and consistent. There was only one panel that didn’t seem to fit perfectly – one corner of a cover under the seat. There was one small sag in the paint on one left-rear body panel. It was just large enough to see in good light when looking closely, but too small to photograph.

Performance perceptions

The high/low switch really does make a difference in power and torque. In the low-speed position, one can twist the throttle gently until the motor starts to ‘grunt’ and begins to turn. It’s very easy to control the speed and it’s very smooth from a standstill to full throttle. Power and acceleration is strong! In the high-speed position, onset of power is more abrupt. Initial acceleration might be a bit lower than in the low-speed position, but the bike quickly accelerates to about 50 KPH indicated. The rate of acceleration slowly falls off, but the bike continues to accelerate to top speed.

I made a couple of runs using the switch as a ‘gear selector’ of sorts. Switch to low-speed, twist to take off, when moving comfortably along, close the ‘throttle’, switch to high-speed, and open the throttle and zoom! Ok, it’s not a transmission, but I can see the value in saying it has ‘two speeds’.

If it were my bike I would prefer a BMS, a bit brighter headlights, and more light on the speedo.

All in all, the bike felt solid, and is a comfortable, smooth, and quiet way to get around. I can see using this for most of my daily driving around – bank, store, post office, etc.

Re: 2009 XM-3500 A Bit DIfferent

The actual capacity of LFP battery in this shipment is 55AH instead of 40AH in 2008.

The same size but 55AH at 2hr. Andy might compare the range with old version XM3500li.

Box in truck

A liftgate would have been nice but this'll work

The box helped stabilize the steel frame. Unfortunately, the box tore one front corner, and the front frame shifted. The left handlebar grip pushed thru the box. The three layers of plastic and bubble wrap on the bars worked and there wasn't a mark on the grip or the chromed end cap.

Connectors in the wiring harness are waterproof and locking

The speedo is only lit from one direction, but the important parts are readable

The VIN is on the plate riveted to the right side swing-arm, and under the seat storage bin

The helmet hook carries over from last year. The 'ignition' switch has a slide cover, and there is a handlebar lock

MC,
Is this "new" LiFePO4 battery in the 2009 XM-3500Li labeled as 40 Ah or as 55 Ah?

What is the "real" capacity of the "60 Ah" battery in the XM-5000Li?

Thanks, Gary

Hi Mountain Chen! Happy New Year! I hope the year of the Ox is good for you.

Can you say when the batteries changed? The cells in this bike (sn 00003x) are marked as TS-LFP40AHA. My friend hasn't done any long riding yet, so I can't compare range.

Thanks! Andy

Gary,

Supposedly the 40Ah cells are made in a different factory - Thundersky Ningbo. I don't know if they make the 60Ah cells.

I have a 40Ah cell and have done some discharge tests. The picture below represents the first 6 discharge cycles on a new cell. The loads are 20A, 40A, 50A, and 60A. I expect they'll 'grow' a bit more capacity as they break in. 40A is a '1C' discharge for this cell, and 60A is '1.5C'. It's hard to read the little graph...the bottom scale starts at zero and each major division is 5Ah. This cell is an 'honest' 40Ah.

Re: 2009 XM-3500 A Bit Different

Maybe the bikes are all in transition, as opposed to being 2008 or 2009 models. Those tailights are certainly different from my XM-3500Li from last year, but the locking connectors and waterproof sleeves on all of the wiring is the same as what I have on mine. It sounds like that wasn't completely true for all of the 2008s, though, if electromotion's post is any indicator.

Re: 2009 XM-3500 A Bit DIfferent

The VIN for the "2009" model is 5XWMLE0569Nxxxxxx where the "9" indicates 2009.
The "6" before the "9N" is a chack-sum digit and xxxxxx is the serial number.

The VIN from a "2008" XM-3500Li is 5XWMLE0578Nxxxxxx where the "8" = 2008.

Re: 2009 XM-3500 A Bit DIfferent

How do we distinguish the "improved capacity" batteries on
the "newer" XM-3500Li Scooters from the "original" (40 Ah) batteries?

What battery "model" does one order to replace a "new" battery so that
the replacement is not mismatched with the rest of the pack?

What battery does one order to replace an "older" battery so that it is
not mismatched with the rest of the pack?

If both the "older" and "new" batteries are labeled the same (as ...40AHA)
and get mixed, this is likely to cause significant problems, especially
if one "older" battery is put into a "new" battery Pack!!!

Re: 2009 XM-3500 A Bit DIfferent

MC,
You saying that there are two different "varities" of the TS "40 AH" battery?

Or, that the 1C (1 hr) discharge rate for the battery is 40 Ah but that the
2-hour discharge rate (0.5C or 2HR) for the SAME battery gives 55 Ah?

If the 40AH battery has been improved, is there also an "improved" version
of the TS 60 AH battery used in the 5000Li?

So, what is the "real" capacity of the "60 Ah" battery in the XM-5000Li?
At 1C and 0.5C (1Hr and 2Hr) discharge, what is the capacityof the TS 60AH?

This is an important issue, please clarify.
Thanks, Gary

Hey Lenny! I don't know when the transition might have happened. I wasn't sure what to expect from the wiring harness - especially after reading electromotion's posts. That's why I took a look around, and pulled one of the tail light sockets.

I had a Suzuki 650 road bike years ago when I lived in England. I had to clean and tighten all the push-in 'bullet' connectors three or four times per year. I was very happy to see the connectors in the 3500. No bullet connectors AND no carburetors to keep clean and balanced?! - Life is good! :-)

Re: 2009 XM-3500 A Bit Different

I would like to hear others experience with three main issues that effect both the 3500li's that me and a friend have. They are both late 2008 models.
1.Handle bars point slightly to the right when going strait.
2.Both tires are out of balance and so far have not been able to balance.
3.Brakes squeek and drag.(reducing range)
Also you have to lean way right to stay in balance when you take your hends off the handlebars.(don't try this if your not experienced)Don't get me wrong I have great hopes for the future of these and other electric scooters. There's something really amazing about the feeling you get when riding one. I love it.

One thing I noticed about this bike is the fit and finish of the body panels. The panels fit together well, seams are even, and all fasteners were tight.

The bike I rode was a 2009 version, and I only had 10 miles or so on it. The handlebars were straight and the bike seemed to track straight hands-off. The tires seemed round and balanced. There wasn't any brake drag or squeak.

Disk brakes don't have return springs to open the pads, and the calipers slide on a pair of pins. Brake dust and crud from the road will get on the brake assembly, the pads, and the pins every miles the bike is on the road. Inspecting the brakes to make sure the pads are free to move around, and making sure the pins are clean and lubricated is part of brake maintenance. A good shot of brake cleaner from time to time is an excellent starting point for any disk brakes.

One thing I noticed about my 5000 is that, while the wheels are round and true, the Chen Shin tire on the back seems to have a bit of a wobble - like it's not quite round. That's a condition that can't be fixed with balance weights. I plan to get my money's worth from the current tires then replace them with something from Michelin, Pirelli, or another manufacturer.

Re: 2009 XM-3500 A Bit DIfferent

I wish someone would clarify about the amp hours on those batteries. That could end up being a real problem if people mix different amp hour batteries. I'm back in Florida. I'm soldering my Fechter/Goodrum BMS while my Hyperion charger balances my pack. The first group of six took 33 hours! Nothing like soldering components that are 1/32 of an inch apart! Are we having fun yet? I'll post any performance improvements when I'm rolling again.

Bill-

Thanks Ross for the reply...I kind of doubted that it was a coincidence that me and my friend had the same problems exactly.

Re: 2009 XM-3500 A Bit DIfferent

I wonder if shipping the tires with over 50 (or 55) psi in them (and them staying that way for months) could "stretch" the tire unevenly?

At least the rear tire on my 5000Li appears to have that problem. I have not checked the front yet. I was getting a lot of vibration when I rode to the DMV, but I assumed it was poor road surface.

Do you mean the 55Ah comment from Mt Chen? I'm not sure where that comment came from. TS makes 40Ah cells and 60Ah cells. I can see that the 60Ah might only make 50 or 55Ah at higher discharge rates, but all the LiFePO4 I've tested drop off at higher rates - A123, PSI 10Ah, TS40Ah, and TS60Ah.

Bill-

It's tedious work, Bill, but worth it! I'm still connecting the TS charger to the bike's stock charger port, so I'm not charging thru the BMS, but the bike's been on the charger for more than 18 hours and the cells stay under 3.9V during the 'charge pulses' and the pack gets balanced! I can ride, plug the bike in, and walk away, knowing the battery is in good hands.

You know, Gary, that reminds me. The USAF sent me to Korea years ago and I left my car in the garage for six months. I never could get the flat spots out of the tires after that. I have no idea how long the bikes spend in the racks, but it certainly could be a factor in the roughness.

Re: 2009 XM-3500 A Bit DIfferent

That's it you guys nailed it. To be precise I bet it's the way they put the tires in the channel THEN inflate them till they are very tight. Thats it they aren't out of balance they're out of round. I just got a new 3500li and so far the horn, turnsignals, don't work. The left main frame tube where it bends to meet under the luggage rack, the S bend is not even with the other side it is VERY noticable. (I might post a photo) I haven't ridden it hands off yet. On the bright side I told X-treme about the fuel gage going out and that the speedometer was fluctuating (which just started recently) on my other 3500li, and they sent me a new panel right away. All my experience with customer service has been good so far. Anyway the brakes on this one are squishier than the other one but there seems to be less drag on the front brake as well, haven't checked the back yet. But guess what tires are out of round. So the track record there is not to good.

Re: 2009 XM-3500 A Bit DIfferent

This is great info since I'm considering an XM-3500li.

One factor essential to my decision is the length of the bike.

The measurements that I obtained from the web site are: 79" (L) x 23"(W) x 47"(H)

Would someone let me know specifically the length of the XM-3500li?

I live in a hi-rise and need to use a freight elevator to put it in the storage area.

Diagonally, I have a length of 80", so there is no room for guessing.

Re: 2009 XM-3500 A Bit DIfferent

I think you're in. I got 77" with the front wheel turned. The only problem is if you get a pod.(and you will want one) that will blow you're budget. I would go for it though I have two of these scooters one just past 4000km and the other about 3300km. That would be cool if you can do that. I have a ramp to my front porch and I can park mine in the livigroom...and do sometimes,no worries about oil leaks! Check out current motors though, they are selling bikes with BMS, regen brakes, higher speeds, better frame and more. I was at a mall in Florida and was looking for a socket and couldn't find one outside. Inside the big sliding double doors was a whole row of sockets. I wanted to just pull right in so bad and charge but thought that might be pushing it.

Wow! Thanks for this info. I'm walking a fine line with having an electric XB-600 with my building regulations. It's considered a bicycle. Now, I also want the XM-3500li because of performance. However, I risk not getting a permit in my building for storing a moped. I may have to keep it in my condo, if that were the case.

At least, now I know that technically, I can get the XM-3500li up an elevator.

The only problem is if you get a pod.(and you will want one) that will blow you're budget. I would go for it though I have two of these scooters one just past 4000km and the other about 3300km. That would be cool if you can do that.

There's a lot of cool discoveries that I'm making with the electric bikes.

I was at a mall in Florida and was looking for a socket and couldn't find one outside. Inside the big sliding double doors was a whole row of sockets. I wanted to just pull right in so bad and charge but thought that might be pushing it.

I'm carrying a long electrical extention cord just for those moments when I can plug and charge somewhere, especially when I stop to eat somewhere.

I would patronize a restaurant that had outlet sockets for use, and would pay additional for that.

Fast forward ten years, we'll have electrical recharging with cordless connections.

Ok, maybe fast forward twenty years.

Re: 2009 XM-3500 A Bit DIfferent

Yeah , that's half the fun, finding cool places to plug in and meeting interesting people.It's 25 miles to the nearest grocery store from my place in Florida. They don't mind they let me pull right up to the front of the store and plug in while I shop. Yes I'm excited to see what's in the pipeline down the road too.

PS my measurement is not perfect but close.

Re: 2009 XM-3500 A Bit DIfferent

I bought one of these 2009 XM-3500 new on ebay for less than what it would cost me to replace the SLA in my EVTA R-20 with LiFePO batteries. I haven't ridden it too much (7 km) since it's been so damn cold, but my experience is right in line with these posts - mis-shapen rear wheel, panels fit well, batteries easy to access and after the initial charge, the batteries balanced very well. I'm also taking it easy on the scooter while I'm waiting on the v. 4.0 Goodrum-Fechter BMS to be available. This scooter appears to be an outstanding value. The only issue I have is what to do with the R-20 now?

Enjoy your xm3500li. I got mine working after 3 days of problems, and I am not in love with this bike. Wheels and brakes are balanced and bike handles well.

One love, one heart, light up the darkness!

Re: 2009 XM-3500 A Bit DIfferent

your tires should true out after about 1000km of riding. You might notice a slight shaking at a certain speed, but nothing severe. I put a Kelly KBL12251 controller on one of mine and kept the stock one on the other. Regen braking is great if you are doing allot of city driving. For open road stuff it's not that helpful. I have been running mine at 28cells or 90v nominal and had no problems with the stock motor or controller after 4000km on both. I get 54mph top speed, which is fast enough for these scooters. Spray your brakes with brake cleaner frequently to keep them from dragging and squeaking.

2009 XM3500li is definitely much improvement than 2008 XM3500li.

2010 Version would be even better included BMS,shock absorber,MP3 and digital speedmeter !
