Context: DJI enters the e-bike market
DJI (the Chinese drone manufacturer) launches its Avinox M1 motor in 2024. By 2026, it equips models from Amflow, Mondraker, and several boutique brands. Impressive marketing announcement: 105 Nm torque, 850 W peak power, 800 Wh battery in the frame. Here's the reality.

The 800 Wh battery — the real innovation
Avinox offers an 800 Wh battery in a standard downtube (40×80×450 mm). That's 50% more than the Bosch PowerTube 500 Wh at equivalent size. High-density Samsung 50E cells (5000 mAh/cell), 80 cells in series/parallel configuration (14s 6p).
Real-world range (measured on Amflow PL Carbon, 75 kg rider, mixed rolling terrain):
- Eco mode: 130–150 km
- Trail mode: 80–100 km
- Boost mode: 45–60 km
Compare that to a Bosch CX + PowerTube 750 (~110 km in Trail): equivalent range despite 50 Wh less, thanks to superior Avinox motor efficiency (87% vs 80% for Bosch CX by independent measurement).
How it compares to Bosch CX
Avinox advantages:
- +15 Nm torque vs Bosch CX (105 vs 90 Nm) — noticeable on takeoff and steep hills
- +100 W peak power (850 vs 750 W) — more aggressive boost mode
- Motor 35% lighter (2.52 vs 3.9 kg)
- Native app without mandatory Smart System — direct Bluetooth connection
- Free OTA firmware updates for life (Bosch charges for some features)
Avinox disadvantages:
- Sparse aftersales support in Europe — DJI Avinox lacks Bosch's dealer network; if the motor fails, expect quick return to Shenzhen factory (4–6 weeks quoted)
- No legal unrestricting possible (no equivalent to Bosch Dongle)
- Limited diagnostics — the app reports basic error codes, but no detailed logs like Bosch DiagnosticTool
- Weak market penetration — few bike shops trained to service them
