Trike Recumbent

I spent a lot on the donor vehicle, so will have to save up to proceed with motor project. In the mean time, I have discovered that Trike riding is a little harder than standard bike but Far More comfortable. I Love riding it and Im getting better at it. You can really feel the lower wind resistance...

Oh, thanks for the tip. I thought these were 1000 cycle things. I imagine a years worth of commuting would be 210 cycles, so 4 sets of batteries a year would really "upset me ".

then there's the rear one and wheel covers

Image

Each additional slipstreaming device can add a couple of Km/h
at the same power input. Weight goes up too , so a stop start commute
doesnt gain as much from them.

My plans include improvements such as this Front Fairing

The fairing gives a little weather protection and reduces the wind resistance.

Thank you, I forgot about the effect of controller in limiting the current. Thank you for answering my questions. You are right - I would benefit more from lower gearing.

Some Questions; 1. is there a typical C rating for these 2400mAh Li-ion batteries? I know it depends upon internal resistance, but this info not given in advertisement. 2. The BMS has an overcurrent protection system. This motor I have chosen is capable of drawing 130A and blowing up controllers. If...

Yes brushed motor, and the efficiency is only stated as >75 %   so a bit wasteful I think. I dont mind changing brushes occasionally [ although I cant see how you get at them ]. The higher efficiency Brushless were a tad heavy. [ but quieter & probably less maintenance] . The cost was also higher. J...
