Hi, I will be making a bid on a abandoned e-bike at a auction.There is no model of the bike or rear hub motor on it. It's a 18 speed mountain bike. No battery, don't know if anything works or not. Any advice appreciated
What's a fair amount to bid

Is that the bike from the police auction? Black with some funky bag on the rear?
I was trying to figure out if that motor was a Clyte or something else. could be worth a few bucks, but could be a large chunk of junk.
I would say open with the minumum bid, Then only spend what you are willing to gamble and lose.

Main Question: how long has that battery been sitting in the evidence room? Could be buying a bike that needs a $500 investment up front in addition to purchase price. Can you go there and try before you buy? Can you strap a meter to the battery and see what is what? Many large investments have started with bargain up front costs.

$50 bucks max. You can't test any of it till bought. By $200 you can get stuff you know works in the for sale used section.
Used battery is always worth 0 dollars.
Rethinking, more is justified if that motor is a 5304, but you'd recognize one of those by the look.

Good call on that one. It was in fact the one with the funky panniers on it. Well I took a gamble and bid $180 and won the auction. It is a Chinese made bike. Has some good products in the build. RST CAPA T-8 Suspension forks. Gossamer FSA pedal system. I took it to a electric bike shop and they said it all worked great. It has a rear 36v 750watt rear hub motor. I need a battery unfortunately. Any suggestions on buying a 36v /15 amp lithium battery. I guess I will go with Ping unless you guys can give me a better option. Thanks.

Congrats! Post up some close ups of the motor and controller, and any specs you can get from either. Does it say anything on the motor cover? Does the controller give a max amp rating?
Ping might be OK, but you might want to go for higher C rated battery if that motor is amp hungry.

I would think with the 750w rating, it doesn't have much more than 22 amps controller in it. So a 15 ah ping, or similar size lifepo4 from sunthing on ebay should work fine.
Also, you could run it with one of EM3ev's batteries, or any number of options. I just wouldn't recommend the really small bottle and frog batteries for that motor.
Cool you got it, and cooler still it's all ok. My lowball bid advice was based on the possibility that you were bidding on just the bike, and the motor was broken in some way. Good deal at what you paid, now that you know the bike was actually worth more than $50, and the motor works.

Thanks guys, you would be of great help if you can figure out what kind of motor and bike manufacturer. As soon as I get it back from bike shop. They are tuning it up for me. I will take some pictures and post them. I believe I read on the controller it said 36v 22amp max. I see BMSbattery .com has some interesting batteries at better prices than ping. I will see what other say about this company. I know Ping has a great reputation.

you found out what rear motor it was? also i find in funny that in the question someone asked if it was a ebike and the answer was "no". lol the auctioneers know nothing. Go to BMsbattery.com they have the cheapest battery options
Btw like i said in the thread i made about the bike, i'm pretty sure it's a yescomusa kit. http://www.ebay.com/itm/Rear-Wheel-Electric-Bicycle-Conversion-Kit-24V-36V-48V-250W-500W-700W-800W-1000W-/290754592384?pt=LH_DefaultDomain_0&var=&hash=item43b252fe80
it even has the same rim sticker

Yes, It was really odd that they answered that persons question saying it wasn't a electric bike. Perhaps since it didn't have a battery they decided to label it as just a bike. I'm happy they did. The only markings I see on the motor is stamped into the metal casing of the motor. xF 40 1101 0695. I also see a sticker attached stating 36v 26". So you think it is kit someone put together and not a factory made E-bike? Interesting. I can't wait to get it back to send some pictures to guys for more ideas of what I have. Thanks for the tip on the ping I will check that out.

it's defe not factory made ebike, like i said, it has a "champion" sticker on the wheel right? if so i'm pretty sure it's a yescomusa kit, just check out that yescomusa ebay link i sent you. Look at the motor pictures.psychonurse said:

It definitely seems like a generic 28mm wide direct drive motor. Buy it a 48v battery if you want extra speed and hills ability out of it. Even at 36v, it will go faster than you can pedal comfortably and climb moderately steep hills. To 10% grade for sure.

Slightly OT but your situation reminds me that when I take my bike on longer train trips I'll often remove the battery and stow it in my backpack. Then, with desire to remain under radar, if/when the conductor asks me - "is that electric?" I honestly reply "NOPE".
'seems like the auction people considered this the same way.
Congratulations! No BAD eBikes IMO. Post some pics and we'll give up some more info. Conhismotor, Yescom and a few others have used those Champion rims. If you're over 200lbs and ride lotsa miles you'll eventually rebuild that motor wheel with better spokes and rim.

Thanks Dogman. I actually would prefer to buy a 48v battery. Shouldn't I be concerned that the label on the controller says. 36v 22amp I believe. I will be able to look and take some pictures of the bike on Monday. The motor didn't look like the ones you thought on those websites. Again I only looked at it for a few minutes and dropped it off for a tune up. I will try to take some good close up pictures and post shortly. Appreciate you help.

I remember asking this same question five or six years ago. The best answer was to just try it. The only danger is that something in the controller can't handle the 48+ volts and fries. If it does work you saved the bother and expense of getting a new 48V controller and if it doesn't work you go ahead and get the 48V controller.
The controller won't have a LVC that works properly for 48V, but a battery with a BMS has a better LVC built into it.
