About

Battery Stem : The Ultimate Power Battery for Bike Journeys 

Rechargeable smartphone battery for long-distance bike rides. Tested to endure weather conditions. 

Smartphones are an essential part of everyday life, with bicycle ride being no exception. However, the limited battery life of smartphones has always been the biggest concern for reliable outdoor use. 

Worry no more. Our Battery Stem will keep you connected all day long without worrying about the battery life. 

- POWER : Integrated 10,000mAh battery pack 

- LONG : +15 hours' use

- FAST : DC 5V 2A two-way speed charging

- DURABLE : Tested to endure outdoor conditions such as rain and dust

Don't go anywhere. Stay on your bike and keep pedaling. Whether you want to navigate, measure the speed, or listen to music, Battery Stem will power your mobile device and keep you on your track. Push forward and enjoy the ride! 

There are two parts in Battery Stem: Stem part and Battery Part.  

Approximately 10,000mAh battery pack is integrated in the Battery part with protection from overheating, overcharging and overvoltage for your safe riding. Also LED lights will show you the remaining capacity of the battery and tell when to recharge it. 

Another advantage of this product is that it is also the first battery-integrated bicycle stem that is made of carbon fiber. Carbon fiber is one of the novel materials for its high stiffness and low weight and has been used for high performance bicycles. The Stem part made of carbon fiber will protect the battery from external shock. 

1. The BATTERY : Certified 10,000mAh battery pack. That's about ...

2. The ARCHITECTURE : Battery Stem Architecture is designed by bike nerd engineers 

- Using carbon fiber, the super battery will be protected from external shock. 

-  Tested for rough weather conditions. Water resistant and dust resistant. Go out all day everyday.

- Protection from overheating, overcharging and overvoltage.

There are many great bike computer mounts available on the market, but there aren't so many for smartphones. Designing smartphone mounts can be more difficult, because there are many different sizes of devices. However, we approached the designing process from a slightly different perspective. We used carbon fiber spring. By simply adjusting the opening of the carbon fiber, we can easily fit any sizes of smartphones.  

Smartphone mount has the perfect combination with Battery Stem. However, it works with any kinds of square stems. 

'PiBike' is a team of bike loving engineers. 

Our scope of scientific and mechanical study ranges from quantum computing to aerospace engineering. But we decided to make something a bit closer to earth - something we can use everyday doing what we love to do; hence the idea for Battery Stem was born.

Risks and challenges

- Our fully-functioning prototypes were presented in the London Bike Show 2018 with warm reception.

-Our products are now prepared for the mass production stage, all except for necessary technical certifications to ship them all over the world.

-The certification cost is quite high, which is why we need your love to carry forward with this project. Other than that, we tried to lower the cost as much as possible to provide these handy bike accessories at affordable pricing.

- We are very confident about the timeline once certification is underway, and we promise to keep you updated in the case of any abnormalities.
