Instructions

  1. Purchasing Equipment

    • 1

      Buy an engine that will automatically convert your bike frame into a gas-powered vehicle. Companies such as RevoPower and HandHeldItems offer 23-cc internal combustion engines that fit between the spokes of the front wheel, endowing the bike with 20-35mph speed.

    • 2

      Ensure that a throttle control and a fuel container accompany your engine. This equipment allows you to regulate the velocity of the bike cum scooter.

    • 3

      Opt for an engine certified by the Environmental Protection Agency. This ensures the engine's output will run more efficiently and emit fewer harmful chemicals into the air.

    Disc Brakes

    • 4

      Install disc brakes onto the bike. Automobiles use such brakes, making them a choice fit for your newly motorized bicycle. Remove the front and back wheels. Place a metallic disc brake rotor onto the center of the spokes for each wheel. Screw in the rotor bolts, one at a time, onto the wheels.

    • 5

      Remove the existing brakes by dismantling their screws with a 5-millimeter Allen wrench. Place durable plastic caps on the bike's brake supports.

    • 6

      Mount the rear caliper with mounting bolts and washers. Install it with a caliper mounting bracket behind the tabs on the lower part of the bike's frame. Install the front caliper with the same tools and positioning.

    • 7

      Determine the needed length of the silk braided cable housing. Measure from the top of the brake lever to the front caliper. Run the cable housing down the frame of the bike.

    • 8

      Remount the wheels using a Torx head wrench.

    Installing the Motor and Twist Grip Throttle

    • 9

      Remove all accessories and extraneous equipment from the bike. Place a 24VDC motor with gear drive between the bike's seat post and the lower frame.

    • 10

      Fix the engine in place. Mount it to the lower frame using a metal clamp on the rear studs. If possible, also screw nuts and split ring washers alongside the clamp; tighten these as much as you can, using a wrench.

    • 11

      Repeat Step 2 with a clamp (and nuts and washers) connecting the engine to the seat post. Ensure the engine is high enough that the petals do not scrape it when they are turned.

    • 12

      Fit two 12DVC 18AH batteries into the engine.

    • 13

      Loosen the lock nuts on the throttle adjuster of the handlebar, using a wrench. Turn the handlebar's cable adjusters clockwise.

    • 14

      Employ a Phillips screwdriver to take down the throttle's screws. Gently disconnect the throttle's top and bottom components. Pull the throttle's cable ends off of the throttle's detents. Remove the throttle grip from the handlebar.

    • 15

      Mount the twist grip throttle onto the handlebar. Push the throttle's cable ends back onto the throttle's detents. Reconnect the throttle's top and bottom components. Replace the screws tightly.

    • 16

      Twist the handlebar's cable adjusters counterclockwise. Fasten the lock nuts of the throttle adjuster.
