Consider for a second the purpose of this forum...
Whenever someone asks a question like this, they're after more than what is asked - they're looking for personal opinions, problems & solutions, the highs and lows of actually building and riding a motorized bike - if they wanted a sales pitch, they probably would just "take 5min and call one of the retailers" but I like to think we offer more than that.
This forum exists to assist people, with the direct experiences of the consumers themselves. While it's true that they may have their own biases, may not even be all that experienced - at least you know they won't steer you towards a different, less appropriate product just because it's got a higher profit margin.
You may have noticed we don't tell people to use the search, that there's no question too basic or too oft repeated here -
this forum is open to all motorized bicycle topics, to all builders - the aspiring dreamers, the first timers, and the experienced professionals alike
