Scooter Engines That Will Fit on a Bicycle

The bicycle is the most efficient form of transportation in terms of distance traveled per calorie expended -- more efficient even than walking. But a bicyclist may want an extra boost to climb hills, go long distances or keep pace with motor vehicles. To give your bicycle extra oomph, you can attach a scooter engine. Read on to see what types of engines you can use.

  1. Gas or electric?

    • A fundamental question is whether you want to use a gas engine or an electric motor. Each has advantages and disadvantages. Gas engines win when it comes to power and speed, and you don't have the added weight of a battery. But electric motors are quieter and don't produce fumes and smoke. Circumstances and personal preference dictate whether a rider is more comfortable mixing gas and oil to put into a two-stroke scooter motor or tracking down a power source to plug in an electric scooter.

    Two-stroke Best for Gas

    • If you're going with a gas engine, a two-stroke that runs on a mix of gas and motor oil is your best bet because they tend to be smaller than four-stroke engines and have a bigger bang for the buck. A downside to a two-stroke engine is they tend to produce more smoke and fumes than a four-stroke.

    DIY or Kit-built?

    • If you're a hardcore do-it-yourselfer who's looking to save money, you may want to scavenge a two-stroke engine from a leafblower, weed-whipper or some other such piece of gas-powered equipment. However, if you want to spend more and save some hassle, you can buy kits for less than $200 that include a two-stroke motor, gas tank, muffler, chain and other parts you need.

    Electric Engines: DIY or Conversion Kit?

    • Here again, the choice is yours whether to do it yourself, or go with a kit. It's a little harder to scavenge a good electric motor for a bicycle, but a potential source is an electric motor from a treadmill. On the other hand, if you opt for a kit, many electric motor conversion kits are available online. You can find kits for less than $200.

    Go for a Ride

    • Once you get your motor-powered bike ready, put on a helmet and take it for a spin. Look forward to some great gas mileage. You can expect about 150 miles per gallon with a gas engine and even better mileage with electric. Be sure to check with local authorities to make sure your new creation is street-legal.
