Well it's been several months since I've posted to the forums. I had a 408/4012 rear hubmotor installed in my velomobile but removed it due to some perceived limitations. With the c-lyte motor and 48v 18Ah SLA the weight bothered me. I was able to obtain my desired range of 26 miles on a single charge with an eight or so hour recharge but that was really taxing the SLAs. Fearful of rear wheel problems such as a flat or spoke breakage I removed the hubmotor. I thought about going to a chain drive system. That was ruled out due to increased interior noise. I've toyed around with a push trailer. It works well and can be removed in a mater of seconds so I have a pedal powered only velomobile. I'm not entirely happy with that setup and have decided to go back to a hubmotor.
One of the problems I had with the c-lyte setup was the coging. My velomobile can coast very well. The motor coging was slowing me down and I also feared the voltage that was being generated back through the motor controller into the batteries would/could damage the motor controller.
I'm thinking of trying a rear geared hubmotor now. I'm also going to change batteries and go to Lithium system. I haven't figured out which batteries to use yet, ping batteries or the ones GGoodrum is associated with. I don't know if GGoodrum battery system is ready yet. Anyway back to the geared hubmotor. I need a rear hubmotor because my velomobile is a tadpole style trike. I have a 26" rear wheel and the two front wheels are 20"
I'm looking for a rear geared hubmotor that can take at least a five speed freewheel. From what I'm reading the "new" Puma motor can only use a single speed freewheel or perhaps a three speed, I don't know, I'm confused. The rear dropouts are 135mm on the velomobile. I'd also like to not be limited voltage wise 36v-72v would be ideal.
I have a couple of other recumbents now so the velomobile would be used for commuting purposes mainly. I'm hoping to get going on the refitting in a few months.
Any advice on batteries or drive system would be appreciated.
Thanks,
