Quality piece of engineering

Hi All,

The motor is an 80cc push bike (bicycle) engine kit from ebay here

http://www.ebay.co.uk/itm/80cc-2-str...item339592a5b1

Couple of 40 schedule pipes to make frame, girder forks from u.s.a. off amazon (not cheap!!) and built a stainless petrol tank to look like a board tracker.

The build has come in at less than £250 all in with new tyres, handle bars etc etc.

Just got to finish wiring it (1/2 hour max) and fire it up...the kit comes complete with a fuel tank should you want to use it as is.

glad you like it...more pictures on here https://www.facebook.com/DastardlyRacing

looks great, still so annoying the stupid laws about using them on the road needing an mot, tax etc....

daveyjones · 30-10-2014, 05:44 PM

That's why its a pit bike..every other country has push bike lanes use mopeds etc etc Great Britain is well behind with its antiquated laws in my own opinion.

They reckon about 35mph in standard trim but you can open the baffles up in exhaust which apparently gives a lot more power but more noisy too.

plenty of sites showing tuning tips heres 1
