On Aliexpress sell many sets for conversion into an electric bike, but due to the large size shipping is expensive and takes a long time. Today, Ali showed me an inexpensive kit that free craps from Russia.
For $ 210 you can buy a set of a 26-inch wheel and the motor 350 W (power for optimum nonextremal urban travel). You can select the front or rear-wheel motor (put forward much simpler).
Included wheel itself (if it forward, it is sufficient to reposition the camera and the tire and set to large), a controller, LCD screen, panel with three control buttons, with two handles brake braking sensors, throttle trigger, assisting sensor installed on the sprocket pedals.
The display shows the level of battery charge, speed, mileage, travel time, assisting level and even the current capacity of the motor and the battery voltage.
Additionally, the battery will need. You can buy it ready, and you can save yourself and collect the cells from the 18650, for example, from Liitokala 18650 2500 mah INR1865025R 20A
($ 21 for a dozen). If you collect the battery of 20 cells will 36V 5Ah, if 30 - 7.5 Ah, if 40 - 10 Ah. Except the batteries need more balancing payment (I took Now a $ 7) And charger (I took powerful 5 amp for $ 27But you can take and 2-voltage half the price). Homemade battery can be placed in a bag on the frame.Batteries, BMS and charging I bought for mowers ( https://ammo1.livejournal.com/1069589.html), but no one bothers to use them on the same elektrovelike (because I'm not going to mow at the same time and ride a bike). In general, I put it in your favorites, and wait for the next sale with the distribution of coupons. :)
P.S. The best photos of electric bicycles with reviews. ;)
