I've just bought a strimmer and found a good way to mount an engine with friction drive,
it combines the advantage of front wheel drive a rear wheel drive, you have the shaft moving along the bike frame from the front (overhanging the front wheel) down to the tire with friction drive, you don't need to change the strimmer in any way so it's quite a good idea for commuting
