Hi Louis,

I open this new topic to better focus on the regen brake of your kit. What is the test result of the regen brake on your geared hub motor? If it does not work, do your team plan to make it work on a geared hub motor with no mechanically freewheeling mechanism or simply on a non-geared one. Thanks.

Hello Derming,

we have sent Dan a new pack for him to continue his review. We have to wait until he get the new pack and make a test if there is a reverse voltage when brake levers applied. That would be a direct evidence.

We confess the combination of a rege controler with a geared motor maybe not very obvious in the "rege effect", we are working here wish to improve this if possible.

Thanks.

Regen has never been my major concern, Louis. The electric brake is what I want. Do you have a non-geared hub motor that can match the controller for sale? I am more than happy to try one if the low rpm performance is good enough to climb slopes. Thanks.

Derming,

the rege and EABS is combined together, we are also having the test this week to make this more clear for the markets. If necesseary we will "renew" the concepts of the rege and EABS. Relatively we like more freewheeling when power cut off compared with rege, this could ensure a longer range and easy the riding.

Thanks.

Hi, I'm new to this board, but have been around ebikes a bit.

I take it EABS stands for something like Electric Auto Braking System. I think most informed people would say EABS has a lot more value than regen in normal use. Freewheeling is also a very good thing.
How about a switch to disable EABS when Freewheeling is important. That way you save brake pads on BIG hills AND allow freewheeling when it helps.

Don, welcome to register with us, wish you will be happy with our forums.

With the controller there is jumper responsible for the EABS and also regenerative braking. Disconnect it then you disable the EABS.

We had test in our lab shows there is a reverse current when braking lever is applied, this reverse voltage will last for several seconds then disappeared.

The problem is the effect of EABS is not obvious with the combination of a freewheel geared motor. You know the advantage of the geared motor, its disadvantage is when you use a regenerative controller with it you could not feel any e-braking or regenerative braking effects.

If anyone have one of our controller in hand, and also he has a brushless DC hub motor, he could try to connect our controller with his own motor, then he could "feel" the EABS when riding.

cheers.

I have a solid 1000 miles on my 48v front hub kit. The first 150 or so without the front brakes due to compatability problems and impatience. Like he said the regen. is nominal. I have recently connected a cycle anylyst to confirm this. If you flutter the brake or the throttle you get a negative wattage drain that could be called regen.. I've played with this a little. I think even if it did have regen. I wouldn't use it. I live in a hilly area and commonly reach downhill speeds of 40 to 50 mph. The freewheel combined with the amazing gearing in the motor allow it to be ridden much like a normal bike. In fact I often just pedal my bike to the mailbox (mile or so) without the battery. So if this kit doesn't regen. one thin amp it more than makes up for it with the ability to change gears to maximize battery range and freewheel to allow pedaling and downhill speed.

Very Interesting. This is the first report by our customer who use cycle analyst to prove the existence of the "negative voltage". We could prove this in lab easily but it is hard to know this for a customer if they donot have some meter or such a cycle analyst in hand.

This reverse volatge is created by the motor rotator, but as the motor is freewheeled, rider could not feel its existence without using some meters to measure it.

Hi
I've seen on your website http://fusinmotors.com/e-bike-conversio ... -kits.html at the 10 main feature regenerative controller work perfectly with geared motor. Does this meant regeneration work fine just like with other kit, with an average of 15~35% of regeneration depending on hill?

Your product haven't freewheel so it can handle regen, but i've still a few question:

Is your product compliant with EU law (25km/h, no assist without pedaling)

Do your controller are programmable. I wonder because I see universal controller elsewhere, which haven't nominal wattage. So i have to specify limit current (5,2A) to not being illegal (250W max in EU) ; but it seems than controller with a rated wattage are nominal wattage and the peak power output can exceed 250W, that's what I want.

Are you doing the 250W 48V kit, because your site didn't mention it?

How can I purchase your kit, worldwideelectricbikes doesn't seems to exist anymore it redirect me to godaddy.com a domain seller.

Thanks
