Yes, a 4.3:1 ratio seems too low for a 700 lbs. vehicleJust started work on this.
It has a motenergy 1003 should be the double brushes.
I have 2 modules from a BMW I3 that I am testing. I gave it a spirited tool around the neighborhood, maybe 20 minutes, and there is a faint electrical smell coming from the motor. Are these things temperature protected at all? I am familiar with brushed motors I used run the ADC 8" in a civic (since gone ac-51) I know they get hot. This is direct drive (4.3 to 1) so maybe all the low speed take offs??
The bike is also probably at 700 lbs Is that too much for this motor?
Thanks for any info
Bike looks great, Zap! I'm thinking about doing something very similar. Did you just mount all of the batteries in the sidecar? What size batteries are you using?Just started work on this.

Great question. On the flat it works fine. I thought for climbing hills and motor longevity I would do the reduction. I just looked at the numbers for the AC-30 motor I am going to put in place of the ME1003. HPEVS said that the obsolete AC-30 has similar power numbers to their current AC-35. If this is the case then I probably don't need to bother with reduction.In post 11 you say every is fine. In post 12 you're asking about reduction gearing for the drive set-up. What's going on?
