may be I am stating the obvious but with two motors, it seems that you are going to install them at the front. How do you keep both motors running at the same speed when going straight and at different speed when cornering?

totally agreed.

I have not heard of an 8-Fun CDkit damaged because it hangs so low. On my Specialized, the BBS01 is about as low as the bottom of my chainring. The motor casing is also pretty solid.

you would need a lot of experience to make a two wheel front drive system. If for any reason, one of the two motors loses power, you will lose control of the bike's steering. As a novice, your choice is therefore pretty limited, either a rear hub motor or crank drive. If you are not worried...

Crank drive is the simplest solution to convert this bike. If you want a road legal crankk drive kit, your choice is limited at present to 8-Fun BBS01 15A 250W, widely available, or if you are in the EU, Woosh GSM 18A 250W kit, which has slightly stronger output. A few UK pedelecs forum members...

the BBS01 design is pretty successful in combining simplicity with low cost and robustness. If you enlarge the gearbox housing, you will increase the torsional stress on the bottom bracket shell.

It's not a realistic scenario. You try to equate a BLDC motor to a resistor, which it is not. It's more like a water wheel. If you hold the terminals of a 100V battery directly to any two legs of your BLDC motor, the current will be so high that your motor will die. In a normal situation, the...
