Tech terms explained.
Quick reference for the technical vocabulary used in our product descriptions.
- Volt (V)
Electrical voltage. Higher = more top speed, more aggressive response. Sur-Ron Light Bee: 60V. Talaria MX5 Pro: 72V.
- Amp-hour (Ah)
Battery capacity. Larger Ah = longer range. Realistically 1 Ah ≈ 1-2 km in off-road conditions.
- Watt-hour (Wh)
Energy = V × Ah. More useful than Ah alone for comparing batteries with different voltages. Example: 60V × 32Ah = 1920Wh.
- Watt (W) / kW
Motor power. Peak W is burst power (10-30 sec), nominal W is sustained. 5000W peak ≠ 5000W sustained.
- Range (km)
Kilometers per full charge. Depends on rider weight, terrain, riding style. Producer claims usually ideal conditions — real-world -30%.
- Torque (Nm)
Rotational force. Higher = better 0-acceleration, better steep climbs. Electric motors deliver peak torque instantly (unlike ICE).
- Controller
Electronics that manage current flow to the motor. Controller upgrade often boosts peak power without changing the motor.
- BMS
Battery Management System. Balances cells, protects from over-discharge/charge, prevents overheating. Without BMS, a battery can fail or catch fire.
- Mid-drive vs hub motor
Mid-drive: motor at the pedals, uses gearing. Better for steep/off-road. Hub motor: in the wheel. Simpler, cheaper, lower torque.
