Re: Considerations on parallel drive set-ups

Mud, could you find links to the parts you mention, so I can get an idea about what you mean. I have read that when you have lots of power, you don't need as many gears as before. A common front MTB chainring set and derailleur would very cheaply provide 3 gears for pedaling. If what you are describ...

Re: Building a pusher trailer

I read about pusher trailers for a while. I may still make one later, but for now I'm going with a bike hub-motor. I remember having some of the same questions, and what I recall is that having one powered wheel on a 2-wheel trailer is not a problem with the handling. I went as far as buying a 20" B...

Re: Considerations on parallel drive set-ups

RH pedal and motor: Advantages - Allows the possibility of using hub gears for the pedals and motor. - Allows use of a rear disc brake Disadvantages - Limits number of external gears on rear wheel (I believe Miles has 5 gears?) Also for those interested in right-side parallel-drive, consider trike h...

Re: EducEco-EcoMarathonShell

Excellent work Louis!, so if the kV is 220, and the battery was 24V, the motor spins at 5,000-RPM? This sounds like some of the RC-motor builds in the "non-hub" section.

25-kph to 30-kph equals 15/18-MPH.

Louis, what is your design philosophy and advice for an e-bike to get better range?

Re: [RCG] How to Convert an Alternator to A Motor

Sounds interesting Ron. Auto salvage yard alternators come in many sizes and are cheap. I was just recently thinking that it would be good to have two bikes instead of just one. This might be a fun project to try !

I don't think so, but I don't know anyone who's tried modifying an old fridge. Two systems that are growing in popularity are geothermal ORC, and concentrated solar with heat storage. As to geothermal, not every place has 300F+ within 1,000-ft of the surface, but its a great option for anyplace that...

I hope this is "on topic", but I was looking at thermometers for controllers and hubmotors.
