    I am thinking of building a bike with a leaf blower on the front wheel, but instead of friction drive using the air tube and nozzle ducted to turbine type blades on the spokes,does anyone know of a good leafblower?? brflg

    Welcome to the forum. The wind turbine drive sounds very difficult, unless you use an engine from a Harrier to power it. With that sized motor (leaf blower), I'm afraid you will have to settle for chain, belt or friction drive.

    But UK e-bike regulations limit you to 250W, right? That's not really worth the trouble if you ask me. Do you think you could use a "250W" rated motor to deliver larger amounts of power as needed with an alternator as a power source? I don't really understand your angle here. But I admire your spirit of ingenuity.

    Using the leaf blower as a pure reaction motor (jet engine) is likely to develop more thrust at cruising speed, and less noise overall, than puffing at paddles on the spokes.

    hey in response to the leaf blower concept: try seeing if Husquavana make them, their stuff is always pretty, very good.... but you might want to look at a site called " www.instructables.com" there are often good ideas, an some hints

    there is hope, someone has made a bike with a leafblower to propel it

    I just don't know how real this is as there is no you tube vid to back it up

    Well....we used to use a big leaf blower and just sit on an automotive creeper, and we could get maybe 3-5 mph out of it.

    So, with a leaf blower on a bike, you may have a little less rolling resistance, and hit 5-10 mph. Lot's of noise, not much speed, and you would definitely have to pedal on any type of hill.

    With a reaction motor, you get more impulse from the motor the faster you go. To put it another way, the closer your vehicle gets to the exhaust velocity, the more HP you net from the same jet of gas.

    it would just be really hard to pedal at 200mph XD

    which is why i am going to put "turbine" blades in the wheels as it might be more efficient at 20mph-35

    I doubt it. You should try both ways; my experience working in aerospace makes me believe your proposed solution is naïve and unlikely to work as well as you think it should. Remember that the bottom of the wheel is motionless with respect to the ground! Where do you think your vanes are going to push it?

    Ahh, but the wheel pivots(rotates),and therfor the bottom of the wheel would move toward the back thus giving the bicycle a forward motion,like a water wheel,or generator turbines in a dam(not a cus word this time) power plant

    If one exhaust pipe will push....what about eight?

    I know, I know, this is an old photo and many have seen it before but I just couldn't resist the temptation here.
