Default Scottys bikes

I have made many motorized bikes over the years and would like to show you some of them.
I made this one about 5 years ago, The engine was noisy, smelly and unreliable but this build made me see the light. Running the motor through the gears is the only way to go!

is that a front free-wheel system? and if not, how in the world did you manage on the pedals?
that bike is an inspiration thank you for posting pics of it and if you have any pics of current bikes I sure would like to see those as well

This bike drove the pedals via the left crank, the motor freewheeled if off so I didn't have to turn the clutch or chain. It wasn't too bad pedaling constantly until you get to a tight corner.(you have to pull the clutch in to stop the pedals turning and catching the road.) I seem to remember a top speed of 84kph down a slight hill (50mph?) although I was also pedaling my butt off.

The later bikes all freewheeled for safety but I have since changed to GX35 Honda power.

I have to find some more pics...

wow
just wow
I'm having a hard time getting my head around that
a few years ago I was in South Carolina with a friend and we went riding our mountain bikes. no motors on 'em. we went up this long curving hill, not a very steep one, but it was very long. I asked my friend if we would be coming back the same way, he said yes we were. after we got to the top and a little ways past it I set my cycle computer to show my max speed as the largest number for when we went back.
the downhill ride was the fastest I have ever been on a bike. 42.5 miles per hour was the reading as max speed so I had to have held it at least 4 seconds. the bike was going so fast that I could not pedal any faster.
I truly admire your skills

The car I was overtaking at the time had a confused driver too.

Im used to going much faster on my motorbikes but I find taking this or any machine to its limit to be just as thrilling.

I dont know the brand other than Chinese. Its a Fleabay special 49cc 2 stroke.

I changed to a pocket bike 49cc 2 stroke on the next bike but it went too fast.

Now I use the honda GX35 4 stroke which is perfect, 100km to the litre (or 240mile to the gallon I think), at about 30mile/h average speed, and no stinky exhaust.

This is the first freewheeler, way too fast. The frame failed at the downtube after 1000km.
