    Last month as a newby I received some great advice from you all. I'm still saving to get a motor for my mountain bike. While browsing the net I found the Honda Island Hopper GX-31 kit. A friend's nephew has offerred to install whatever I buy for me. I really enjoy riding my bike and am just looking for a motor to assist me since I am an older grandma and have knee problems. Do you think this motor would be a good one to buy for what I want?

    Binkie, I bought a Honda GX35 about 3 or 4 weeks ago. It's mounted on a friction drive set up from It's a sweet little engine. A little less power than I would like. My bike and I weigh close to 300 lbs. combined. If your combined weight is 200 lbs. or less you'll probably be very happy with it. I've had no issues with the engine or the drive kit.

    Porkchop, how does it take the hills?

    on some hills you may have to pedal a little so as to assist motor

    should be maybe 3 times easier than just pedalling up most hills ??

    hopefully Porkchop will get back with you before long

    Thanks MM! I do want to have enough power when I need it but don't want to depend on the motor all the time. While I continue saving, I'll keep researching too.

    hard to beat it for all round riding motor or not

    hard to beat it for all round riding motor or not
    and very very super simple

    the good old friction drive

    when THINGS are dry outside ((having had no rain)) we have a nice little motor bike
    working all so fine at getting us from point A to point B with no break downs
    and very nice for when we just wish to ride bicycle
    a simple lifting of the drive unit -- approx time required 3 seconds
    and we have a bicycle with ((no drag)) what so ever from the engine

    it's a sweet super simple mb thing

    it means the island hopper set up has a drive roller that is smooth.It doesnt have a ruff surface like these.

    My Harbor Freight 50cc 2 stroke with a 1.25" roller pulls way better than the Honda GX35cc 4 stroke with a 1" roller. No comparison. However I put my money on the Honda as far as longevity ! And for what it's worth, the Honda takes me about 12 miles on a tank full of gas. (factory mounted tank) I don't remember the calculations but I think it was about 100-120 MPG. I personaly don't think you'd go wrong in choosing any of the Japanese engines in the 35cc - 50cc range.

    Thanks!!!! You all are being so wonderfully supportive. I sincerely appreciate it!

    I looked at the Mitsubishi 42.7 last night as another option. Any thoughts on this one?
