i'm thinking of powering my bicycle with a small rotary engine. does anybody know of a company who manufacture small rotaries ? who has got one for sale? please let me know: microe45 at gmaildotcom many thanks!
you are right. even their smallest ones are far to big and powerful. 1 or 2hp would be fine. a rotary of that size should weigh no more than 300-500 grams. imagine something like that inside the front wheel...
The only Sachs engine I can currently find at smallenginewarehouse.com is a normal (but very ancient) 90cc two stroke with a huge round fan shroud on it:
thanks guys, sachs did a chainsaw back in the 70th using a wankel power. and never again... i heard it wasn't popular because it didn't have a chainbrake.
I just saw on some other forum that it uses 25% oil mix. So you'd probably leave a black trail on the road behind you and a string of car crashes where ever you go. There are a couple of those engines on ebay, about the cost of 2 new GX25/35's but a wankel engine on a bike would be fierce unusual altogether
