NOTE: The BadassBox enables motor assistance up to approximately 35–37 km/h but does not maintain accurate speed data on the onboard display. As a result, riders must rely on external GPS devices (e.g., bike computers or smartphones) to obtain correct speed readings.
In contrast, the EPAspeed BOX supports assisted speeds of up to 50 km/h while preserving full accuracy of the factory speedometer — offering the most advanced contactless tuning solution currently available.

❌ Conventional Tuning Chips |
✅ EPAspeed BOX |
|
Installation Time |
Tool-free installation; mounts on the chainstay in approx. 1–2 minutes. |
Same fast installation time (1–2 minutes), with a more secure and vibration-resistant fit. |
|
Maximum Supported Speed |
Assistance typically increases up to 35–37 km/h, depending on wheel size. |
Same assistance range of 49-50 km/h, but with higher measurement accuracy thanks to improved sensing. |
|
Speed Display Accuracy |
Output speed on the bike’s display becomes random and highly inaccurate, requiring an external GPS device for correct speed readings. |
Maintains correct display readings using a 1 : 2 speed-correction algorithm, providing accurate speed feedback without external devices. |
|
Battery Lifetime |
Approx. 5,000 km or ~6 months under regular use. |
Approx. 8,000 km or ~12 months, depending on conditions — engineered for extended service life. |
|
Build Quality |
Uses standard materials; the pin-lock mechanism is prone to wear and may break under repeated removal or vibration. |
Reinforced enclosure designed to lock directly into the speed sensor with enhanced durability and anti-vibration structure to prevent failures. |
|
Included Components |
Box, magnet, battery. Spacer not included, which may be required for some chainstay geometries. |
Box, magnet, battery. Includes multiple spacers, anti-vibration shims, and zip ties for universal and secure fitting. |
