Company YKsuccess has a 800watt 48volt hub motor, controller, and tire with tube for $340 some dollars. That includes air mail from china. It took ab amazing four days to get here. It's perfect! I bought another battery from Xtreme ( just the batteries ) and mounted them under the seat. It's a tight fit but they fit. Then I solders a plug from the pwr supply of an old computer (they're the same as on the battery) onto the new batteries so I can use the same charger, and useing the female pwr cord from that old PC, I wired the old battery to the new battery in parallel so as to keep the 48 v but increase my amps to a 40 amp nominal rating. My 700Li goes almost 30mph even up 8 to 10 % grades. It's wonderful. I can still take out both battery packs and charge them or leave them in and charge them.
Now for the head lights. I used luxeon rebel stars. They are 500 lumens each, they were bought from ledsupply.com. I also bought the small sq heatsinks for them the have self adhesive thermal tape on them so the rebels just stick right to them. I also bought from thunderstorm.Com a 48v to 12 v converter to use. Now what I did was to cut the existing white bulb mounting brkt in hal. And mount the rebel stars right inside of it. They fit perfectly , I couldn't believe it , then just twist mount them back into place, wire them to the converter that was wired to the old lights ( I connected both hot wires for low and high beams together ) and use the gnd wire from only one buld. DON'T LOOK INTO THESE BULBS!! they are killer bright.
Ill try to attach pics soon.
Thanks for the writeup! For my windshield, I just cold bent it, since the curve I needed wasn't so great. I tried heat bending some samples, but I never got confident enough to risk a full sheet of lexan in the oven.
Hello all, sorry I havent posted in a while,been busy with different projects including my Amped/Juiced riders test bike! pics to follow! Hey Dave, I need more info on the 700 mods!
Very cool! I looked around YKsuccess's site but didn't see the motor/tire combo you mentioned. What model is it?
Excellent! I was wondering about that pedaling gear. Nice to know it just unscrews,... and threads for it on the new one?? Nice!!
This sounds like a perfect upgrade motor.
I'm a little confused about the 16" rim though. My XB-508 has a 12" diameter rim, even though the tire is marked 16-3.0
In looking at the specs on x-treme's site, it states:
XB-508 - Tire Size: 16x2.5 on 16" Inch Aluminum Wheels
XB-700li - Tire Size: 16" x 3.0" on Aluminum Wheels
In fact all the XB series are listed as 16" wheels. So my question is, what is the actual diameter of the rim you received? What size is the tire marked?
2nd question: How much clearance does your 700li have between the rear forks where the motor slides in? Was there room to spare or tight fit? The forks on mine have 6-1/4" gap between them, will it fit? (Fingers crossed.) The slot on the forks where the axle slides in is about 3/8". (Will grind wider if need be.)
Yes the 6-1/4" is the spacing between the mounting points on mine. Is that enough for this to fit? If so I will be ordering one right away! :-)
Thanks! This company you found is a major find! I want to make sure I get the same model you did so it will fit.
In the 800W 10" category on their page, I see 3 different models:
SXLG-08 ("with gear"...wonder if thats the pedaling gear?)
I'm guessing you asked for the 04?
P.S. ...OK final 2 questions before I order. Did you order the disc brake or drum brake?...And, you also mentioned the rim looks very similar to what you had, so it will still look stock. Which picture on their site looks like the rim you got? The SXLG-29 looks the closest to my stock rim.
Thanks again for sharing your great find and for your help.
well with that motor you might need one lol, awesome mods though. it makes me wonder why these battery powered things don't always have LED lights. Price I guess....also i don't think 700li could go much faster than what you've done and be safe.
what if I just bought the motor and not a new controller or more batteries? I think with the batteries it probably just wont last as long?
Nice to be back after a computer meltdown. I just sent Susan an email to buy a motor. Now time for batteries! I'll check into Optimum-China. I've been running my XB-508 with it's 550 watt motor with the 72 volt and shunt mod every day for just over a year now rock solid even on a couple of 105 degree days. It does 26MPH and climbs hills ok but I expect a nice improvement with this motor. I'll let you know how it does at 60 and 72 volts.
I picked up a tip on the XB-600 forum here about tires that have been a great find: "
www.BikeBandit.com has some cheng shins for $14 ea!
Select the 90/90 - 12 option. They are for 12" rims. They replace the "16 x 3.00" tires perfectly. XB-500, 550 and 600 owners who have tried them all swear by them, including myself. They have 2-3 times the tread thickness of stock XB tires (eliminating my flat problems), and the tread extends up the sidewalls which improves the cornering ability and comfort immensely. At 14 bucks each they are a great find and overall ride improvement.
You say, "I do hear and feel the steering column shift when I break hard/fast which is from the front fork shaft having to much play in the column." I agree with the diagnosis, but I am VERY surprised if there are NO bearings in the head tube. The XB600 has conventional head tube bearings. It's hard to properly set them up, as they need a ~50mm spanner which, in turn, won't fit behind all the "stuff" around the head tube. I've ended up using a punch, and tapping the lands to tighten the lock nut.
Setting up the head beagrings is an important safety maintenance item. At least in the XB600, the head tube shimmy is really nasty with loose bearings. I'm sure my long legged seating position with the weight very far back over the rear wheel magnifies this.
Thanks soo much for the info RE yksuccess and the hub motor you got from them.
I received mine two days ago and MAN what an improvement! From the time I contacted Sue via E-mail till the time I received it was about 2 weeks and was/is well worth the wait. My XB-700li runs like a champ now.
I'll look into battery upgrades soon after I get this silly grin off my face!! Oh, by the way, they threw in a new throttle along with it at no charge after I told her about the issue you had.
Your absolutely right about the increased confidence now. I'm not constantly looking in the rearview mirror to see what may be about to run my ass over anymore. Now I'm looking only to see if a cop is behind me.
Because of the slow acceleration with the stock motor, I'd always stay as far to the right at any red light/stop sign and wait for traffic to clear. Now I'm up front waiting to take off.
I've already upgraded the headlight, Next, when cash allows I'll be looking into the battery upgrade you did.
Thanks again, I just might chang my monika to SMILINGDAVE:0))
The fact that the bike is supposed to have them does not exclude the rare chance someone may have recieved a bike that did not have them in place. Given the various quality control issues many of these bikes from several different manufacturers have exhibited, if a bike is "shaky" while turning, stopping, or just stiff while turning side to side, there is something WAY wrong! Bearings are usually (1/4", 3/32" or some small size)either loose steel balls or held in place with a fancy metal "bearing retainer" equally spaced around the inner shaft and the outer tube. Here are some technical details from the Park Tool site....
Please note, Park Tool is a leading manufacturer of Bicycle repair tools, and as such this info deals specifically with standard bicycle designs. E-bikes may or may not match any of these designs.
Bottom Line: If your e-bike has no bearings in the steering system, something went wrong that needs immediate attention!
