Here's some interesting sites on converting a pushbike to a high mpg low powered motorcycle. If kept under 25cc, and if you use a sturdy pushbike, I understand you can make these UK road legal using the msvr scheme. You may however need to use a mountain bike with disc brakes, fit a horn and lights, but it seems quite do-able:
Is there any european law governing these machines? I am in the ROI and I doubt I would get away with one of these for more than a few days before I would find myself trying to explain what I was at to one of the states cops.
ut if it has a combustion engine and you've built from scratch using new parts you need a european msva test, which is not very onerous when you keep it under 25cc, above that and it gets the full works. insurance could be under £50 pa?
I wrote to citizens info this morning. I asked them about this. If I get a reply I will post it. 250 watts is 2.5 times what a fit adult can produce- that must make bike- life easier. It is the battery life that I am concerned about. I wonder how a 25cc on board battery charger would go down with the gods? Say, 2 smallish batteries, one on charge and one running the bike. Swap over every 15mins. The engine is not driving the bike.
well if they could do you for a generator that is not directly driving the bike, surely they could do a cyclist with a pacemaker? well, perhaps neither a direct analogy nor a strong (or realistic) defense ...
methinks your potential loophole worth exploring. how small do efficient generators come and what sort of weight are they? How quiet?
i have a bike trailer, what about more batts in the trailer, or indeed a generator in the trailer? what would the efficiency of such a setup be?
