    How about fixing a cordless drill so the chuck rubs on the rear tyre , dynamo style, Ive read that this actually works really well.
    I'd be using a brushless drill and mount with some form of disconnect mechanism

    2nd one in this video ,

    No, chainsaw is the way to go:

    You can of course use an electric chainsaw, which would be much greener.

    In general the purpose built e-bikes with the mid drive systems are really good. They last a long time and have a great range of power because they use the bike gears.

    There are lots of other adapter kits. From what I've seen the Bafang is very good. There are lots of other kits out there and the results are variable.

    Electric bikes are the next big thing as far as most manufacturers are concerned and the choices are growing from all manufacturers. two years ago none of the big names sold an e-bike in Aus. Now all the big brands have several.

    If it's something you'll be riding a lot it's probably better to buy a whole bike with the system built in. The Bosch ones are excellent. We have a bosch integrated gazelle and it's now 4 years old with 10,000k on it. It gets used by someone in the family most days.

    The Kelly boys, Todd and Rick grew up just around the corner from us and one day when Rick was about 15 I spotted him going him down the road on a BMX bike at a rather quick pace, and he wasn't even peddling. I was on my motorbike, so I did a quick u turn and caught up with him for a chat.
    He had a petrol Whipper Snipper engine very professionally mounted just below the seat, with the shaft removed and a knurled wheel instead, that drove the rear wheel of the bike.
    The setup had been built by his father John and had a lever to engage the unit so that the knurled drive cog contacted the rear tire.
    Simple and easy.

    Cheers, Mick.

    This mob, "Blade" do some pretty good electric tredleys.
    I had a spin on a few of their models at a recent Camping and Caravan Show in Mildura.
    They were very impressive, well built, and certainly got cracking, but like most leccy bikes, rather exy.

    I have had a couple of demo rides of Ev bikes and they are great.
    The newest system has a way of measuring the torque input which makes pedalling the same effort regardless of speed. This will be my next demo ride.

    May have been one ot these I passed recently. Girl pedalling at sedate / purposeful rate, seemed constant now that you mention it.. and doing 53km/h on the flat and up a slight but long hill. - No change in pace or speed...
    - Rear hub motor, battery small or very well hidden... Frame ?
