What can I do with this XM-2000?

Last summer, my XM-2000 stopped working. I talked to someone from this board and they said they would figure out what was wrong with it, if I sent out the motor and controller. I dont have a background in engineering like it seems most of you, do, I am just a student that is interested in electric vehicles, so this seemed really nice and I shipped them out. That person never shipped the parts back...

Now I have a scooter with no motor and controller, and I am trying to figure out what I can do with it. I cant seem to find anywhere that will sell me a replacement motor and controller, but I did notice several new scooters being produced by X-treme (the 3500, 5000, etc.). Is there any way I can use parts for those on my XM-2000?

Any other ideas on what I might be able to do with this thing? Anyone else facing problems with a broken part and have gotten them fixed somehow?

I am graduating in May and may move out of state, so I need to figure something out ASAP. I figure either I might be able to get it working and possibly take it with me, or I need to sell it for parts.

How much would you want for it, if you were selling it for parts?

Re: What can I do with this XM-2000?

Raynman,

We can provide you with a hub motor and controller that will work on that bike. However it might be a while before we can figure something out for you. We have a 6kW motor in a 10inch rim which can be used with a Kelly controller and should fit on your bike. You can also use XM-3000 parts - motor and controller. The tricky part in all this is that the XM-2000 used a drum brake on the rear and all the newer bikes are disc brake on the rear. So you'd need to buy a rear disk brake assembly (easy) but you'd also need to modify your swing arm to fit it (not easy for you but relatively straightforward for someone with experience welding).

Good luck.

Re: What can I do with this XM-2000?

A great question. I paid $1800 for it. I don't know what a motor and controller run, but I know these are the main components of the bike, so I know this greatly discounts the value. I guess I am open to any reasonable offers.

Re: What can I do with this XM-2000?

NICE! Is a 6kW motor 3 times the power of my 2000watt motor that came with the XM-2000? Is that principally why I would need to change the braking system?

I think getting this thing going again is the best option I could hope for, for getting the most value out of the bike both functionally and dollar-wise. How much to get these parts from you?

Would a different braking system be needed for XM-3000 parts? Checking the reviews, it doesnt seem like the XM-3000 went any faster than the 2000.

Re: What can I do with this XM-2000?

The reason you need to change the rear brake system is that the XM-2000 rear wheel has an integrated drum brake and the new motors have an integrated disk brake. It would be the same issue with the XM-3000 or with a 6kW motor.

When switching from a drum brake to disk brake you need to mount the brake caliper on the swing arm - that means welding a plate onto the rear swing arm. However, I just noticed that Kelly do motors with drum brakes.

You'd probably do better buying the motor and controller from Kelly Controls (http://www.kellycontroller.com/shop/?mod=cat&cat_id=16) - rather than from us. They're set up for customer support on individual products - we focus on supporting our bikes. You'd be looking at between $400 and $500 for the motor and between $300 and $450 for the controller.

Re: What can I do with this XM-2000?

Alrighty, I am trying to figure out which motor and controller to buy from kelly. I would really like to try to keep it down to about $500, but recognize that the increase in power (speed?) might be worth going a little bit higher?

if I were trying to just get back to waht I lost (2k motor and controller) can you help me telling me which controller to get? I dont see a 60volt model that seems to fit...

Also, id like to solicit opinions on going from a 2k motor/controller option to something higher in power? how much speed difference would the 2.5k or 3k give me?

The XM-2000 bike is 60 volts, right?

Re: What can I do with this XM-2000?

increased power will get you increased acceleration.
top speed is limited more by back emf.
so you want to pick a motor that has a voltage the same as your battery pack, at the speed you require.

so if you have a 60v pack, this might mean that you need a 48v motor and a 72v controller.

Hi,

For motors:
http://www.kellycontroller.com/shop/?mod=product&cat_id=16&product_id=383
http://www.kellycontroller.com/shop/?mod=product&cat_id=16&product_id=384
http://www.kellycontroller.com/shop/?mod=product&cat_id=16&product_id=386

These motors are all for 10" rim and have a drum brake so would be a "drop in" replacement for the XM-2000. Note that you will no longer have a low seed / high speed switch. But with one of the controllers below you can set things up to give you better throttle response.

For controller:
http://www.kellycontroller.com/shop/?mod=product&cat_id=41,22&product_id=152
http://www.kellycontroller.com/shop/?mod=product&cat_id=41,22&product_id=155
http://www.kellycontroller.com/shop/?mod=product&cat_id=41,22&product_id=153
http://www.kellycontroller.com/shop/?mod=product&cat_id=41,22&product_id=156

Using a 72V controller with a 60V motor is fine - but you'll need to use the config software (a free download) to configure appropriately. You also want something that is rated with high enough amps to be able to handle two to three times higher than your motor. The above 4 controllers are 100A and 150A (two without regen two with regen). 100A * 60V = 6kW [peak] and 50A * 60V = 3kW [continuous]. 150A * 60V = 9kW [peak] and 75A * 60V = 4.5kW [continuous]

So those controllers give you good "head room" when used with any of the above 3 motors (2kW, 2.5kW and 3kW). The motors should be able to safely handle 4kW, 5kW and 6kW peaks - and probably more.

(And as Matt says - a 48V motor would be a good option as well (and would save you some money))

John,
How did you manage to get the specifications for these motors. I looked over the Kelly website, and didn't see any links for spec sheets. I would like to find out the max rpm for each of these, and for other kelly motors as well.

Re: What can I do with this XM-2000?

I looked into these as possible upgrades a few months ago. I was about ready to do it too. Then I saw the shipping cost. Might want to check that out before you start sizing up controllers and motors into your budget. The shipping costs just might bump you back down a bit.
