Hi all, I am new to this forum and new to e-bikes. Last week, there was a surprise auction for a new/used e-bike store that went bankrupt. I thought it would be a nice gift if I bought my son a bike. Unknowingly, I purchased this bike that has no battery or charger and also no manufacturer's name that I can find. If anyone can help, it would be immensely appreciated. Thank you. Ps.: I am not even sure if the motor is still good. Is there anyway I can test the motor before I buy a battery?

I don't know, but I don't think I'd buy it. There are some red flags:

  • There are a LOT of tubes in that frame, it's going to be REALLY heavy
  • It says "EMTB" = eMountain Bike, but it is clearly not that. It's a comfort cruiser
  • "EV DC BRUSHES MOTOR CONTROLLER" should be "BRUSHLESS" This level of inattention to detail doesn't fill me with confidence that everything is well sorted out.
  • What's up with that ENORMOUS headlight and fuel gauge? Adding more weight just for the sake of it.
It looks like something cobbled together in someone's garage, which is fine if that's what it's advertised as. But if it's supposed to be a commercial product, it doesn't look like a quality one.

Thank you for your points. I have already purchased this bike on an on-line liquidation auction. I have to deal with it now. I am a senior that does not have much knowledge in e-bikes. I appreciate the knowledge that you taught me and will always consider your points in the future if needed. Thank you.
 
I saw the 'brushes' thing and was thinking it may not be a mistranslation of 'brushless' but instead an Engrish version of what we call 'brushed', which is even worse.

Big points to the OP for trying to do something nice for someone, but I'm afraid it is unlikely you will get this thing to work.

With that said, the controller label does tell us that the battery system is what is known as '36v'. A 36v system has a full charge/discharge range of roughly what you see on the label. Actually the peak is 42v but the label more or less encapsulates the 36v range. Its certainly not 24v (the next step down) and it ain't 48v, whose range is way out of whack with that label, so you need a 36v battery.

What that leaves for you to find is a 36v battery that fits in that space. Your next move is to get a pack with open leads - a red wire and a black wire. Those are easier to find than you might think; especially if you are willing to use a set of nippers to make them bare leads. Then you find the corresponding wires on the bike and make your connection manually with a crimp or a solder. Carefully, and hopefully only if you know what you are doing.

Thats what its going to take to bring this bike back from the dead... assuming the motor still works.

Be advised this is how all those bike shops and apartments in NYC burn down... Well-meaning people doing inexpert work. If you don't have the experience to do this sort of thing, there's no shame in that.

EDIT: It is entirely possible this bike is so old it was meant for use with a lead-acid battery and not li-ion.
 
I like it , its nice and shinny .

If it never see`s the road, it will make a great dust catcher..... in any home .
 
According to the links, a brushed motor and a lead battery.

The frames seem to be highly regarded, by some, less so by others. Heavy. Can fit a li-ion battery and new motor fairly easily.

Brushed motor from that time frame MIGHT be a Heinzman, which were highly regarded, German made.
