Aotema bike kit
I recently purchased an Aotema E-bike kit from Berson EV. When the front axle nuts came loose the fourth time, it pinched the wiring and was advised by their tech rep to purchase another controller and that would probably fix the problem. It did not. I again contacted Bernsov and explained the problem and asked if I could return the controller. I received an E-mail back telling me it was a matter of personal responsibility and that this was not a repeated problem with this hub motor. When I recearched this on the internet I find that there are several people that have experienced the same problems. I, then contacted Wilderness Energy Systems and received ZERO help from them. MY ADVISE, DO NOT PURCHASE ONE OF THESE KITS. YOU WILL PROBABLY BE WASTING YOUR MONEY.

Re: Aotema bike kit
Sorry to learn of the problems, but anytime a "Hub Motor" comes loose under power, it is likely to result in wiring damage! Extreme care must be taken to ASSURE that it will not come loose, as it would then rotate the axle, twisting and possibly damaging the wiring. (this could happen to a hub motor from ANY company, if allowed to come loose!) Better means of secoring it, possibly with an added brace, seem to be required in your case, and the wiring will need to be repaired, as it may be broken, separated from its internal connections with the motor, or shorted.-Bob Curry

Yeah... I can't think of how the controller would make any difference unless it was a less powerful controller.

Re: Aotema bike kit
Hate to say this, but nuts coming loose is your problem, not thiers. This is a common thing when people unfamiliar with ebike hub motors install them improperly. Usually they are making the mistake of using a set of forks made for a quick release hub, or sometimes just a fork that has weak dropouts to save weight. Bike coice is very important, and unfortunatley the sellers just say, " put it on a cheap bike" and don't say why, or give any info on whay type of steel front forks are a good choice. The second most likely cause is not using the washers that come with the kit properly, or at all.
The same dang thing happend to me, in the first half mile of the first ride. WE happily sold me a new controller, since the shorted wires blew the first one. I do agree though, that getting Aotema stuff from the vendors you mention is not a good idea.
The guy to buy Aotema stuff from is High Tech Bikes. He has excellent customer service, and can help you with any problems you have, so get your new controller from him for sure. Then install the motor, after the wires are repaired, on a set of strong forks with lots of steel in the dropouts. Usually bmx forks or beach cruiser forks are the best choice. Stay away from anything alloy, or just too light if it's steel. You want a dropout designed for a bolt and nut, NOT quick release.

Re: Aotema bike kit
I accepted the responsibility for having the axle nuts come loose and would recommend that anyone that installs one of these motors buy and install jam nuts to prevent this from happening. This kit was installed of an Schwinn cruiser bike and I thought the forks would have been stong enough to handle the torque. Thanks for the tip of going to High Tech Bikes. I will contact them to see if they can solve my problem.
