Although I realise that range is dependent upon the weight of the rider and the terrain covered, there must be an average range for a bike equipped with your kit. I would hope that with the type of battery used and the regenerative braking, that range would be better than other systems. Also, it would be interesting to know how many charges these batteries can take before replacement is required.
In order to compete with other systems these are important marketing aspects that need to be addressed.

for a standard 24V/10AH LIFEPO4 battery pack the range is about 30kms, with a load of 75kgs on the bike.

The regenerative braking controller offers a function of re-charge the bartrery when the rider release the throttle bar, or use brake lever, or cycling downhills, the controller will take into effect to brake the controller and revere the energy back to the battery when the reverse voltage is over battery voltage (24V).

So it is hard to tell how many extra miles will be added by the regenerative brake controller, this will depend on how the rider use his bike and the road condition. We made a test in our lab on a 48V system, and the recharge voltage could reach 58V when we release the throttle bar or use brake lever.

Compared with traditional lead acid battery around 300 times circulation for the LIFEPO4 battery it could be over 1000 times.

Thanks for the information, Fusin Tiger. Next point - When you decide to use the bike normally (without electric assistance) can you switch off the power supply from the handlebars, without having to get off the bike? This might be when the road is level (and with no head wind) and therefore, the electric assistance is not needed. In this way, you will considerably extend the range of the battteries.
Also, the folding bike we use has a right hand twist changer for the 7 gears. Would we have to change this, in order to allow the controller for the electric speed changer to take its place?
Finally, with the right hand and left hand brake levers, do these operate conventional brakes, as well as the regenerative braking?

on the bike handlebar there is a headlamp integrated with key lock, just switch off the key the system will be cut off although the battery is still on, then you could use the bike as a normal bike.

In your case we have a thumb throttle instead of throttle bar, you needn't replace the original gear shifter on your bike.

Our brake levers will replace yours on the bike and it works both as conventional brakes and as regenerative braking.
