24V 250W Hight Speed Engine Chain Drive System This item include: 1). 1 x 24V 250W brush motor 2). 1 x Motor controller (with fuse wire) 3). 1 x Key throttle (with battery voltmeter & key switch) 4). 1 x No-teeth freewheel 5). 1 x Chain wheel (55 teeth) 6). 1 x 25H chain (106 links) 7). 1 x Freewheel adapter (27mm) 8). 1 x Headlight with switch 9). 1 x Brake lever 10). 1 x Brake light Note: this kit without battery and battery charger . Controller and Throttle Brake lever Notes: 1). This motor is a high-speed motor that without reduction gearbox, its output speed is fast but its torque is small, so it does not good to drive heavy. Usually we use it on the small wheel scooter. If you do not know what motor you should use, please feel free to contact me. 2). This kit comes with a 55T chain wheel, this can let the vehicle run fast(10-inch wheel about 25km/h), but the torque is low, if you want the torque high, you'd better change this chain wheel to 65T or 80T. 3). This freewheel adapter inside diameter is 27mm, if this size doesn't fit your axle, we also have the 21mm and 31mm models. 4). This kit uses the freewheel chain wheel that can drive forward only, if you want the motor drive backward, you need to use a fixed chain wheel or weld the freewheel to make it fixed. 5). This controller comes with a fuse wire and 3 fuses, if you burn 1 fuse, you'd better note what makes it burnt and avoid this happen again, or please feel free to contact me for help. 6). This kit does not include battery, you need to buy the battery separately, the lead acid battery and the lithium battery are all ok, and the battery capacity I recommend 24V 15Ah.
