Why riders like ARES
No firmware hacks
No wiring changes
Quick setup
Hot-swap battery flexibility
Designed for Bosch BES2
Phone app (Android/iOS) with BLE live battery monitoring
Sealed interface design to reduce exposure to rain, dust, and trail debris
Transparent and practical approach
Why this approach
Designed for practical installation
ARES is built for riders who want a clean setup and a simple experience, without turning the bike into a wiring project.
Built around daily usability
It is made for real use: commuting, weekend rides, and long days where reliability and quick setup matter.
Transparent development
We share what is validated, what is still being tested, and what may change before production. No hype, just clear progress.
Why BES2 riders need a practical alternative
Bosch range-extender solutions are currently focused on BES3, while BES2 riders are often left with improvised setups that require modifications. ARES is designed around the native behavior of the original system, with an integration approach that avoids invasive changes.

Important Notes
FAQ - Do I need advanced bike wiring work? No. ARES is absolutely plug-and-play. You do not need to open or modify anything on the bike. No drilling, no frame modifications, and no electrical rewiring are required.
FAQ - What if the extra battery fails or I want another one? The supplemental battery workflow is based on standard 18V tool batteries. If one battery fails or you want a spare, replacements are easy to find from online stores, hardware shops, or directly from us.
FAQ - Can I monitor the supplemental battery in real time? Yes. ARES includes a BLE module and a phone app (Android/iOS) that shows supplemental battery SOC, voltage, and current, and can notify you about faults or other important events.
