To forget about the need to rotate the pedals when riding a bike, it must be equipped with electric or diesel drive. For long trips certainly better than the petrol engine, as you do not need to do a long stop for 6-10 hours to recharge. Cheapest and easiest solution of all possible, is to install on the bike motor from brushcutters. He has a full-time tank, throttle, clutch, much easier conversion.
- sheet steel;
- shaped tube 20×20 mm;
- led by leading Cycling stars;
- roller chain;
- bearings of different sizes;
- steel pipe of 20 mm, 32 mm and 50 mm.
The installation of the motor
Remove the left pedal from the bike.
Of sheet steel welded platform under the motor mount and bolted to the frame of the bike. It made eyelet holes for regular bolts for attaching the tank to the motor shaft came out on the opposite side of the cassette sprockets.
For more reliable fastening of the plate to associate her with the upper part of the frame. For this from 3 pieces of shaped tubes is welded a U-shaped arc.
At the bottom it is welded to the plate and to the frame of the Bicycle at the top clamped to the pipe clamp from the pipe.
Thus, to the bike nothing is welded. The curve of the arc must allow to freely set the engine.
Then you set the motor without rods with short-cut shaft.
The plate is welded a piece of scrap strips for mounting the tank. It is desirable to place the tank so that filler neck was higher and it was easy to pour in the oil.
On the motor shaft 2 is installed bearing, and pressed by a clamp for fixing the rod. This will remove the backlash at speed.
Then the shaft is welded to a sprocket from an old bike.
Led star is welded on stud that is screwed instead of the left pedal. The right pedal also dismantled.
Stars are connected with a chain. For them tension to the frame of the bike is screwed onto the roller. It is a long pin with two bearings on which is mounted a steel tube.
Then instead of the screws fixing the rear axle in threaded pipe with welded or pressed on the ends of the nuts. This will allow to simultaneously hold the wheel and create a footrest since the pedals on the bike are missing.
The throttle from the engine can be mounted with clamps in a convenient location on the handlebars. Be sure before the test you need to check the brakes and, if necessary, to replace them, because the load on the drive motor will increase.
