Any idea's would a weed wacker be under 200watts
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
