Hello from Scotland UK

Discussion in 'Introduce Yourself' started by Topper Harley ' Scotland, May 23, 2016.

  1. Hi everyone

    I'm Scott from the lovely Scottish Highlands. I'm run a small engine service, repair and Rebuild Business. I bought bulk 8 Hp Cutter 66cc kits last year and just getting round to building a bike now. I've build a few bikes already using different strimmer engines with mixed results. We have lots of long empty roads and trails. I build for reliability and endurance.

    Looking forward to learning more and joining in the craziness on here!

    Welcome to the forums! Hope you have good luck with your 66cc I'm guessing it's a kit?

    Hello from Wales. :) What engine are you using? Are you getting 8hp from a 66cc strimmer engine? I would love to see pictures of the bike you are building with that! :)

  4. Hi sadly its not 8hp. The company who ive bought the kits from is called HP Cutter. I wish i could squeeze 8hp out of a 66 haha.

    Thanks for the warm welcome!

    Haha I did wonder! :D
  6. If I had it would be the greatest tweaking masterpiece ever. I'm guessing my 66 has 2 if that though I'm happy with the endurance and 17mph. It will go a bit faster though I enjoy cruising along

    I think it would take a miracle with the China bike engine. I have a generic 66 too, I'm trying to save up to get a shift kit (and lots of the options). Hoping to get reasonable endurance and mimimal noise by keeping rpm low. I don't mind the lower power either. :)

    I like to go fast so neither could help me none;)

    I know it takes engine speed to produce power; but at ~30mph on flat ground the power is mostly used to fight air resistance. You could probably reduce the air resistance to some extent and go faster for the same power, or the same speed with less power, better fuel efficiency and improved reliability.
    I think gears are part of the solution, along with modifications for "low" RPM range power, but we will see.
    200 watts (an untrained regular cyclist) is equal to 0.26 horsepower so being able to pedal along with the engine could (i hope) give a noticeable boost to engine power at "low" RPM range.

    I agree on gears but if you just want speed who needsm??? A 41 tooth is perfect for speed, and ride ability.... I don't like pedaling (bicycle, motor... Why should I?) besides you can't pedal a single speed bicyclfe that's going 30mph. What's wrong with a Loud exhaust? Makes people look:D.... Even more since it's a bicycle

    Well, the OP of this thread lives in the highlands of Scotland and I in Wales, so we needsm!
    It is cold and wet here, and pedalling makes you warm, healthy, strong, sexy and makes you feel happy. :)
    Even a 48t X 11t combination can easily pedal at 30mph (30.5mph at only 90rpm with a 26" wheel).
    These bikes are illegal on public highways so a system that allows quick tool-free disconnection of the mechanical link between the engine and wheel is a very good thing. ;)

    What you mean? Like the clutch when pulled in makes a mechanical disconnection so the motors drive is no longer connected to the back wheel I tried on a cop he didn't like it but it's true.

    Lol, that would not fly here. If caught on a public highway, even just a few yards from a motorcycle trail, they would confiscate the bike on the spot, leave you out on the highlands to walk home/ freeze to death and they crush your bike and sell for scrap metal.
    The only way to go, as far as I can see is to make it impossible to drive a wheel or start the engine: by removing the right hand jackshaft chain. For this you need the SBP Shift Kit and their right hand side chain tensioner (and no bashguard).
  14. Haha yes here in the UK you would kiss goodbye no matter how much you attempted to prove you're innocence. On top of that a possible 6 points and £250 fine. I'm working on a road legal bike with photos to come though as stated before im not building a bike for speed or performance! I have a motorbike for that.

    Oh just picked up a Motobecane earlier imported from France. I also collect vintage bicycles and mopeds

    Will post a little photo later
