Electric hub that is in regen till throttle pulled

[seanreit]

I can't find anything on this and hope you guys can help.

I think I need a 24" front wheel with an electric hub that is in constant regen mode till you activate the throttle.

Preferable around 500w and 24 to 26 volts. If you can recommend a battery tech that can handle the constant over charging, and if not, I can put in a simple switch.

I have a 24" 1985 BMX Cruiser with a 35 CC Honda engine on a belt drive to rear wheel and a portion of my commute is in a Texas park where I can't run the engine. I won't be plugging the batteries in ever so any charge would have to be gained by the forward motion. The Texas Park part of the commute is about 4 miles which saves me about 20 miles, so the batteries don't have to be much capacity, maybe even 4AH. I was thinking Lipoly Radio Control Hobby batteries in series, but not sure they are safe under regen.

If I understand you correctly, you mean you will never be charging the batteries with a charger and want regen to charge them when you are running your 35cc gas engine. Any direct drive hub motor can do this. How regen works is a function of the controller. Many can be set to regen when throttle is released. The amount of regen can be configured so it would never over charge the battery pack. Should be easy with a programmable controller, but can also be set via hardware with cheap non programmable controller that relies on LVC settings to control the max voltage of regen. Any reason you couldn't just use electric for the whole commute and do away with the gas engine? I think that would be a simpler solution with a commute up to 20 miles.
