Electric Bikes

We customize lithium ion (Li-ion) batteries, lithium iron phosphate (LiFePO4) batteries, nickel (Ni-Cd & Ni-MH) batteries and lead-acid batteries for electric bikes, in styles of Hailong, Silver Fish, Dorado, Rear Rack, Down Tube, Water Bottle, Jumbo Shark, Triangle and other special shapes, which can either be replacement batteries for your already-existed e-bikes, or be customized for your own brand. In addition to electric bikes, our battery packs are also used in pedelecs (e-moped), e-scooters, e-motorcycles, golf cars, etc.


Tailored For Your Applications

RHY’s engineering team takes the time to understand your overall system, then formulates the right battery strategy which is best suited for your requirements. We adopt the right battery chemistry, cell brand, structure, features and program according to your applications.

Excellent Safety & Reliability

Safety is always the first consideration when we make a solution for customers, especially for lithium-ion batteries. Due to the chemical characteristics of lithium-ion battery itself, it is necessary to protect it from overcharge over-discharge, short-circuit, overcurrent and over-temperature to avoid combustion and explosion.

High Performance

Higher energy density, lighter weight, better safety, faster charging, longer battery life, smarter BMS, are our concept and also the trend of the battery industry. With the most advanced battery technology, RHY always delivers the best performance and helps you achieve further breakthroughs in your fields.

International Standards Compliant

Our products are certified by standards like CE, UL, FCC, PSE, KC, RoHS, UN38.3. Our engineers will design and develop products according to the standards specified by you. We can also modify the existing products to meet these standards on your demand.

Battery Solutions
for E-bikes

No one ever complains about having too much battery capacity. Battery as one of the most vital components of an electric bike, decides its speed, mileage and range figures, so it’s always right to use a more powerful and capacious battery.

RHY Battery Solution Brings You:
  • Battery packs with unprecedented strong power and large capacity
  • Tailored solutions for your budget and market
  • Precision molded plastic battery cases perfectly mounted in your bicycle frames and realize smooth and quick removal and replacement
  • Fast and safe charging
  • The battery receives instructions from the e-bike and adapts to different torque and speed modes.
  • Smart BMS with safety circuit protects batteries from overcharge, over-discharge, overload and short circuit, by monitoring each individual cell and balancing the voltage and state of charge among the cells.
  • Integrated MCU communicates with the e-bike and charger to exchange the information of battery voltage, temperature, current, state-of-charge (SoC), etc.
