Most of us can really benefit from a higher than 50cc engine and are responsible enough to keep speeds down but that's not all of us.
But still it would be fun to have the acceleration of a motorcycle on our bicycles but then you have to look into the fact that there is a bonified reason why motorcycles and mopeds have a lot more heavy duty components.
I've looked at my Buggy Bike and I've made some crazy modifications to this Titan kit which is currently now a 3 speed with freewheel I just rode it today to pick up my meds at the local Kaiser and I absolutely love it. Because that Worksman trike is so heavy and it's definitely built tough I could see putting on a higher displacement engine and it would really benefit but I have a side pull brake up front that just slows things down a little and a coaster rear that has been known to derail from the chain. I have even thought of an extremely simple way to get a CVT on that Titan. Buy the CVT transmission and just flip the engine plate so the engine is moved over lining up the sprocket to the jack shaft and you can really get some speeds!
But then how fast do you want to go on a bicycle with bicycle components? Then what would cops think when you are passing mopeds on the streets?
I'm always about tinkering. I'm always about looking for improvements. But after today's ride that vintage 3 speed is shifting ever so smoothly I can finally shift without looking down at where my gears are at I looked at my buggy bike and thought "all I really need for this ride is a paint job it's looking purple today cause some pink over-spray got on it from when I painted that kiddie bike for my God daughter.
So sorry for spoiling the party but the inventiveness in all of us has to reach a summit. And if I go bigger I WILL attract the attention of the law.
So as far as my buggy bike goes,I have reached my summit.
Cronus just needs a new engine so I don't have to share the one on the buggy bike which incidentally has surpassed 4500 miles by now. I've pretty much already reached that summit too. Got the wheelman wheel in back. That's the only mod that bike needs. 48 tooth sprocket is just right for me.
So in conclusion 30 mph for me on a bicycle is way too fast for my blood.
That's just me,but I like it when the world passes by me slowly.
