I got the first recordable amount of regen. back to the battery. It was only .ooo1 Ah but I was excited. I never doubted it but it's still cool to see on the cycle anytst. Thanks again for the exciting product.

many thanks for this. rege works mainly for braking bike actually, we could not count on its charging amount, while it works with a freewheel motor its brake function disappears.( could not be felt by the driver).

For our new-generation kits we will cancel this function anyway.

Derming on our forum has purchased our kit without motor, he has a 24V DC motor so he will connect our kit with his direct drive motor to check if the rege works, we will be expecting his report on this.

cheers.

Wow I can't wait to hear how that works. Will the three speeds still work? If so I might be interested in another controller for a pusher trailer using your battery. Can I buy just the controller?

Yes 3 speeds will be still remained.

What a c ontroller you need? Could you tell us the max amp and voltage you need for this controller?

Just a hint, to check your bike front wheel and secure the instalation, sometimes when it is not installed well the wheel might spin out of the fork and cause accidents.

Thanks.

Not sure what I would need yet. I'm going to build a single wheeled trailer with a hub motor so it can help it's self up hills. I thought regen. brake would charge and act as a trailer brake also. Still in the planning stage. Thanks for the heads up. I'm runnin' dual torque arms from Ampedbikes.com(Steve's suggestion) and used Locktite on the threads. Still I do a full inspection on the front every time I ride. Good idea for everyone.

Nice to hear you have installed torque arms from ampedbikes.

As of you rnew trailer it will be helpful if you have ideas on its loading capacity, speed requirements, climb ability, driving ranges, etc, these will be important to decide setup of a new system.

Thanks,

I've spent a few sleepless nights thinking about it. I'm going to build a single wheeled pusher trailer. Probably a B.O.B trailer. I've been towing my extra battery in my trailer. With the custom trailer weighing 23 lbs. itself. Plus the Sampsonite suitcase at 13 lbs. And then add the battery and mounting hardware at 25 lbs. and I'm towing quite a load. The motor handles it beautifully. I pedal alot especially at start. But I cant climb hills or carry much extra. So what I want is a pusher trailer that can carry 70 lbs plus batteries,assist the bike in climbing hills and still be able to maintain my 25 mph top speed. I think the motor would have to be at least 500 watts, maybe more because of the 16 inch wheel. I don't care much to increase speed, just to not lose speed up hill with a load. I wonder if I used a non-geared motor could your regen. brake act as a trailer brake and gain back some power. Or would the constant resistance of a non-geared motor be too much? By the way I just got back from a 34 mile ride with this setup. 18 miles of it done on a Fusin battery. 16 of it done on the Ping leaving 3.48 Amp hours still on it. Performed admirably.

Yes a non-geared motor will work obviously with rege and EABS, the only problem of it is its resistance when you wish to pedal by man power, since you have got 2 batteries this seems not to be a problem.

Thinking of your trailer project you also have to consider the safety issues, because it might be not stable if drives too fast. As of the trailer if you are going to convert a ready trailer into electric, or you want to make one by yourself?

After much help from the endless sphere guys. I've got two ideas. The simplest being the one-wheel trailer. Just have to watch my speed. What I need for this is a motor wound for a smaller wheel /16 inch with a thumb throttle that has a long enough line. I think a geared motor so there's no drag. So your kit could work. Can it be had in this configuration? Do you make a thumb throttle? The next idea is a two wheel trailer with two motors and two controllers. The throttle and battery connections would have to be run in parrellel so there's only one of each. This seems a bit too complicated for me but is still in my mind. Can you supply a set-up like this? This is alot to ask I'm sure.

48v motor installed in a 16" wheel is not a problem,also the thumb throttles. see herehttp://fusinmotors.com/plugins/content/multithumb/thumbs/b.160.120.16777215.0..stories.ebikekitsf.thumbthrottle.jpg.

If you wish to use 2 motors on each of the trailer rear wheels, you might have to consider the differentials problem, otherwise there might be difficulty in direction turning, anyway we are not very professional in this.

In China people use differential motor for heavy load tricycles, see the attached photo, power could be 48v/350w or 48v/500w, max torque 80NM, output rpm 260, this should be the best choice for trailer applications.
