1 Horse Power = 746 Watts

200 Watts = just over 1/4 HP

Whoever decided upon a maximum of 200 Watts must really dislike motorbikes.

I would think 1KW or 1-1/3 HP would be a more reasonable limit.

All but the tiniest hobby engines are rated for more than 1/4 HP.

You would need something like an early 1900's thumper to be in compliance, and they were too heavy to work in a bike.

I feel your pain...I don't think you're going to be able to find an engine. You'll have to go with a motor and a battery. 200 Watts should produce somewhere between 8-12 MPH

hey mate. i dont think a petrol motor producing under 200w would do anything. ur best best to stay legal is go electric. my mates got a 200W electric bike and it goes bout 20km on the flat with no wind. its alright uphills but needs a lil help.
the onlything i dislike bout electric is having to charge it.

kick his nutts in let him feel like crap but thats me.I may be a small guy but have took lots bigger men than me down to my size after you do it to them they start to understand people a little better.I done it back in school it work then and it work on my job one time too he turn out to be an ok guy after I brought him down to my size.If you don't
do that then I would just move piss on folks like that.
