Motorized Bikes?

Does anybody out there own a motorized bike? They seem to be getting more and more popular these days. Would be interested in seeing your own designs etc.

Ya I will be very interested in some pictures and maybe even a bit of directions.

i just put it together with bits and peices laying around the garage. the mount is mainly old gun racks from older police cars. i bolted a bike peg to the pto of the engine, and that is what spins the tire. i didn't want it to be chain driven, b/c i still wanted to be able to pedal. the only problem with it being direct drive, is that you have to lift the back tire to start it, and then run along beside it and jump on. once its warm though, you just have to start pedaling and it will start. you have to pedel up hills or on grass. works good for going to town.lol

Yeah I think that motorized bikes have become more popular with the rise of gasoline prices and the economy. I live in a small town where everything is close by. Many people here ride bikes, scooters, or segways to work and school.
Personally I have never been on a segway but I would like to try one out. How fast can speeds get on one? Does anybody know?

If you're into serious low-cost transportation, consider a Tomos moped. I have one, rode 7500 km since I got it last spring, averaging 107 mpg. Prices are $1000 - 1700, depending on model and dealer. Look at Tomos. Tomos has been making mopeds since 1954, and their engines are quite good. Their whole moped is good -- durable and simple for maintenance and repair.

If you want a good hobby, add an engine to a stout bicycle, as suggested by other posts. Golden Eagle makes a good kit, sold via internet, with several engine options. But these add-ons are not really serious transportation -- some of the name-brand engines are quite good, but adding an engine to a bike puts a lot of extra stress on spokes, bearings, tires, and brakes. You're adding 12-20 lbs, usually hung out over the rear wheel, and you will be consistently running at higher speeds.

For a cool-looking ready-made motorized bicycle that is strong enough for transportation, check out a Whizzer Bike. A guy in town has one, and it is something people will stop and look at. They are sold over the internet. I think the price is a little high compared to a Tomos moped, but it comes down to personal taste. The original US-made Whizzers are real collector's items when restored.

It looks like they make a decent piece, but their web site is a touch on the lame side, IMHO!! They should out a little more time into it if you ask me...

Yes, I think the web site was designed by the factory people in Europe and translated into English. It hasn't changed in the past two years.

I have seen people riding motorized bikes up and down my street, I think they take them at least 2 miles to school. I have heard they are legal to ride on the street, I am not sure what kind of license you would have to have.

I once almost made a motorized scooter

It was an old school one with oversized tires (6' diameter rubber inflatables) and I had a tiny kid bike with a sprocket on the back tire and similarly sized tire on it so I was stretching the back forks out to put on the sprocket tire then could mount a weedeater engine and put a throttle on the handle bars and hook it up with a chain or whatever..... theres a device you have to hook between the chain and motor but I forgot the name
