Hi all. I'm new to this forum but have been searching through it for months. I'm thirsting for good info so decided what better to do than join up!
I'm planning a build, and decided to buy a single speed urban/MTB bike. Disc brakes a must. I'm considering a Stg 3 motor from 'Rock Solid Engines' as they are an Aussie company. But the more powerful motors out there have cought my attention.
My big question is has anyone fitted a euro air-cooled pocket bike motor like a BZM 420/620, Polini Elite 14 or similar to a bicycle? I'm trying to work out how it would perform without a gearbox. My quick sums say it will do over 60mph with the most practically attainable 6/80t gearing with a 700c wheel. Would this make it a real pig to ride?
I have looked at the Dax 50/Morini style motors and the case size makes them "look" really...well.... Illegal.
I work as a race car engineer (fabricator) so anything is possible for me to make, but I want to be realistic with what I do. Noise is not so much of an issue as I can fab silencers.
Cheers guys
