how to make electric razor scooter?

I need to know how to make electric razor scooter please help!

Since then I first saw those folding aluminum Razor Scooters, I thought to myself "It would be really nice the one engine. "project was always on the back of my mind, has to look twice at me whenever another kid whistling went with me on the sidewalk. However, I could not justify the $ 90 price tag is common to the small scooters, and I should have, choose the court sale a few years. How would it lucky that I drove home from a friend watching a movie at around 1:30 AM and noticed something shining on the road. Sure enough, when we passed, I recognized the form as "Rage" (Razor knock off) scooter. After dropping off my friend I went back hoping the next passer by had picked it up. It was still there, and quickly is the way to the trunk. After some investigation, it was obvious why the junked scooter. Front and rear wheel bearings were destroyed. Seals were missing, most of the balls fell out, and races are run against each other. I think it just shows you throw-away society in which we live round brought a quick stop shop replacement bearings for a whopping $ 9. By bike shop had nothing in stock, I could go to any number of local suppliers Bearings and probably find even cheaper alternative. Now, when I was working scooter, the project could begin. First idea was to fit gas engine. Who wants to noisy, smelly, inefficient and complex 2 stroke engine with clean, efficient and silent electric motor could be used instead? I had more than enough suitable hand engines and batteries are available from UPS, we service work. The only real problem was how to get power from the engine to the ground. Rear-wheel scooter is simply mounted on the bearings without shaft or other method of transfer of rotational forces on the wheel. When searching for one of the many scooter enthusiast site (Scooterworld tzi is), I found that most builders use the drive spindle. They connect the rod or pipe to the crank shaft, and push it to rear tire. This achieves two things: 1 Transfers rotation to the rear wheel, 2. Provides a high gear ratio between the engine and steering wheel , small (large chainsaw) gas engines used. These small engines have no torque, and need ratio of 10:1 and more just to move the scooter. The shortcomings of this design are high energy losses between the spindle and wheel, sliding caused dust or moisture, and extreme places on the tire wear. It would simply not work, so I decided to take a string or a belt. High torque electric motor, in combination with a small 4 "Razor wheels high gear ratios unnecessary. The solution I developed can be viewed here. Existing rear forks were cut off just before the slightly bent inward grip wheels. Slabs of 3 mm steel was then welded site, extension forks and provides space for mounting bearings. A large hole was cut in the center of each plate to provide space for the shaft pass. 1 / 2 "Flange Mount Bearings are used only screw-mounting. Instead, nice and round holes for screws, incisions were made. One of the bearings are horizontal cuts, while others use vertical. In this way, when the shaft-driven, however, bearing himself-unification and make sure the wheels would mount up directly. The shaft itself was only 6 "from hardened tool-steel rods with 1 / 2 "diameter to match the bearings. A major problem was the steering wheel. Plast wheel scooter was 5 / 8 "barrel, and of course there is no provision to be locked to the shaft. Several trips to the local Bearings save turned nothing and rental shop was another dead end. I was at the local Princess Auto (auto / trade surplus), I found two key elements: 1 / 2 "locking collar, and 1 / 2" 5 / 8 "housing. Perfect! It is difficult to see in the picture, but the wheels are set as follows. collar was welded on the large diameter washers and 5 holes were drilled around the perimeter of the pad. Another relevant plate without the drill collar to match. Cases have been installed in the round, so she could sit for 1 / 2 "shaft. On the left side wheels, pad the collar was placed along with the other pad on the right side. Five machine screws were then used to clamp the wheel washers. Locking nuts are installed on the collar side, with his head on the opposite side. The result was a wheel with "thick" and "thin" party, which could easily be locked to the shaft with set screw in the collar. Plate assembly is firmly clamped to the wheel, the actual weight is still concentrated at the center bore. Since the screws pass directly through the wheel spokes, no rotation transmitted to the wheels. You can click on the picture above to get an enlarged view of the rear assembly. Skin
