how do you go about getting in the over 50 mph club.

That's snow country here!
Both the ski resorts are having a nice year with snow making where needed.

We just moved below the snow, 3,100', just right ;-}

You move out of the valley since I left ? You were central PHX right?

Yes, we bought a house this winter up in Camp Verde Chevy.
60mph is not that big of a deal on a good bicycle.

A good 66cc and pipe on nice bike will cruise 60 all day.
Even a 48cc holds it's own with a pipe and shifter.

That would bounce the needle around 50mph.

Bufu has posted videos of himself at speed.
He should have also mentioned a "real head" as well. Burn rate is part of the formula.
You are gonna be spinning the crank up 9000 to 10,000 rpm so maybe some "real bearings" as well.
At those speeds some "real brakes" and real maintenance on wheel bearings, spokes and tires is a good idea too.

SKF make great bearings!that's a great choice,you can allways dill a feed to the bearing to help lube and cool it better!

But I was only on a stock 46cc that hit 65+... now im using a zenoah g43 ported and piped. Changed to belt drive single speed "build in progress"...

Grats on replying to a dead guy. Yeah, he actually died last year.

Also, my throttle-limited Huasheng went 85 in 2016 and again in 2017.

Yeah, so it was bolted onto a bike rack on the back of my BMW. Still.

With a zeda motorsports poor boy motor, mz65 pipe, 32t sprocket, and 27.5in wheels my build shouldn't have any issue hitting 50-51 if you have enough road. So far I've only gone up to 44 mph but the motor was only turning 66-6800 rpm and was still pulling. On a 44t sprocket it's good for 36mph at 85-8600 rpm, 51 or so should be doable with enough room. Not all that bad for a stock intake and stock NT carb with the stock jet.
