About Crf-E2 Electric Dirtbike
Crf-E2 is an electric off-road motorcycle designed for teenagers. The frame is made of high-strength aluminum alloy, which helps reduce the total weight to 48 kilograms. The battery module weighs 6 kilograms and can be replaced in two minutes. A three-gear speed mode and a protected gear shift structure help prevent incorrect operation and support the gradual learning of riding skills. Double shock absorbers at the front and rear allow a shock absorbing range of up to 120 millimeters. The electric drive system is quieter than a gasoline engine.
Press Kit
- Unique Properties
- As a light-weighted field utility scooter for teenagers, it outshines conventional gasoline off-road vehicles in security and lightness. Its whole weight is 48 kg, and the battery module weighs 6 kg, which can be replaced in two minutes. Its three-gear speed mode and complex gear shift structure avoid misoperation and enhance driving safety, facilitating the acquisition of driving skills.
- Dimensions & Packaging
- 1450*910*270mm
- Tags
- ultra-lightweight, strong endurance capacity, convenient, off-road, for teenagers
- Production Technology
- 1. Frame:
It is made of Alcoa-6000 high-strength aluminum alloy, going through forging, machining, profiling and argon arc welding. Then, it undergoes heat treatment, calibration, prescription, sand blasting, and finally anodizing. Only after acceptance can it be put into use when the whole process is completed.
2. Battery assembly:
(1) Sorting and grouping process
(2) Automatic welding process
(3) Semi-finished product assembly
(4) Aging test
(5) PACK detection
(6) PACK packaging - Design Challenge
- The most difficult part in the design process is the fractures of the frame. The original vehicle model was for road driving. Most foreign clients tended to drive the vehicle for the cross-country racing because its appearance resembled an off-road vehicle, but the shock absorption of the original model was not strong enough to meet their needs. It leaded to the fracture problem of the original vehicle model.
- Project Duration
- The project was launched in Los Angeles, USA, in May 2018 and completed in Dongguan, China, in October 2021.
It is expected to hold a press conference in Los Angeles, USA, in March 2022. - Operation Flow
- 1.The ultra-lightweight frame helps to reduce the weight of the whole vehicle to 48kg.
2.The battery-powered dynamic system outshines conventional gasoline engines in terms of less noise, higher torque and better environmental protection.
3.Double shock absorbers at the front and rear sections manage a shock absorbing range up to 120mm, further enhancing the operation.
The complex gear shift structure can avoid the misoperation and allow users to acquire driving skills step by step. - Research
- Studies have shown that more than 70 percent of teenagers tend to spend their spare time at home, which will exert a negative impact on the physical and mental health of teenagers in the long run. In view of this situation, this product can better cater to them in daily leisure. Riding an off-road scooter accompanied by parents in the fresh air is a great way for teenagers to relieve stress, enhance fitness and balance.
- Inspiration
- In view of the increasing popularity of new energy, a new battery-powered dynamic system is developed and applied to the scooter. The simplified battery structure for easy detachment and quick replacement endows the scooter with stronger driving range. In this way, the scooter is an ideal substitute for gasoline off-road vehicles on the market.
