There's nothing in the electrically assisted pedal cycle regulations about needing any mechanical connection between the pedals and the wheels. All they say is that the max assisted speed must be limited, the motor cannot deliver more than the power limit and the bike must be able to be pedalled. A...

Not sure hat your idea was but you'd also have to pedal like mad just to crawl along. not if the gearing between pedal and generator were appropriate - it would afterall just be a much less efficient way of transferring your energy to the drive wheel. (I say much less efficient - what's the efficie...

possibly a stupid question...
Is there anything in the regulations that state how the drive is taken from the pedals to the wheel on an assisted bike?
Say for example you removed the chain and all it's associated gubbins and had a generator attached to the pedals, then a motor on the other end - would that pass scrutiny?!

Has anyone got the lowdown on these and the prices? Cheers, Nino. Haven't got the lowdown on the spec, but I did enquire about the prices of the 90ah cells last week. A mere $135 per cell. At $2700 to power my planned trike I suddenly found the £100 worth of lead acid off ebay really very very a...

However like anything, the terms tend to be used more by those with some idea of what they are talking about. :lol: which definitely wouldn't include me. Only battery powered applications I've ever played with (other than cars) before have been NiCd NiMh or LiPo, so the lead acid is all a bit confu...
