If you’re considering buying your first e-bike, it’s natural to feel a bit overwhelmed by all the jargon and technical terms thrown around. Don’t worry—at Powered Pedals, we’re here to break it all down for you! In this guide, we’ll cover the essential e-bike terminology to help you make an informed decision and feel confident about your purchase.
Key E-Bike Terms
1. Motor
The motor is the heart of your e-bike, providing the electric assistance that makes cycling easier. There are two main types:
- Hub Motor: Found in either the front or rear wheel, these motors provide direct propulsion to the wheel. They’re generally quieter and require less maintenance.
- Mid-Drive Motor: Positioned in the middle of the bike (usually near the pedals), mid-drive motors offer better balance and are ideal for tackling steep hills.
2. Battery
Your e-bike’s power source! The battery provides energy to the motor and is typically mounted on the frame. Here’s what to know:
- Capacity: Measured in watt-hours (Wh), the capacity of the battery determines how far you can ride on a single charge. A higher Wh means a longer range.
- Removable vs. Integrated: Some e-bikes come with removable batteries, making it easy to charge separately from the bike. Others have integrated batteries that are built into the frame for a sleeker look.
3. Pedal Assist (Pedelec)
Pedal assist, or Pedelec, is a system that provides power when you pedal. The motor kicks in automatically as you pedal, giving you a boost without needing a throttle. Most e-bikes have adjustable levels of assistance, letting you choose how much help you need.
4. Throttle
Unlike pedal-assist, a throttle allows you to power the bike without pedalling. Simply twist or press the throttle to move the bike forward. Throttle-operated e-bikes aren’t as common in the UK due to stricter regulations, but they’re popular in other countries.
5. Range
Range refers to how far you can travel on a fully charged battery. The range of an e-bike depends on several factors, including the battery capacity, terrain, and how much assistance you’re using. On average, most e-bikes can travel between 20-60 miles on a single charge.
6. Watts (W) and Watt-Hours (Wh)
- Watts (W): This measures the power output of the motor. In the UK, e-bikes are limited to 250W for road use. More watts means more power, but not necessarily more speed.
- Watt-Hours (Wh): As mentioned earlier, this measures the battery’s capacity. More watt-hours = longer rides!
7. Torque
Torque is a measure of the motor’s pulling power. Higher torque means better acceleration and hill-climbing ability. Torque is measured in Newton meters (Nm), and most e-bikes range from 40Nm to 80Nm. If you live in a hilly area, a bike with higher torque will be more useful.
8. Display
Most e-bikes come with a display unit mounted on the handlebars. The display shows key information like battery level, speed, distance travelled, and the current pedal-assist mode. Some advanced displays even offer GPS and connectivity features.
9. Controller
The controller is the brain of the e-bike, regulating the power flow between the battery and motor. It manages how much assistance you get based on your pedal input or throttle use. Most riders won’t interact with the controller directly, but it’s a crucial component for a smooth ride.
10. Cadence Sensor vs. Torque Sensor
These sensors control how the motor assists you while riding:
- Cadence Sensor: Measures how fast you’re pedalling. The faster you pedal, the more assistance you receive.
- Torque Sensor: Measures how hard you’re pedalling. The harder you press on the pedals, the more power the motor provides.
11. Charge Time
This is how long it takes to fully charge your e-bike’s battery. Most e-bike batteries take between 3-6 hours to charge, depending on the capacity and charger type.
12. Weight
E-bikes are generally heavier than standard bicycles due to the motor and battery. When buying an e-bike, consider how much weight you’re comfortable lifting or transporting, especially if you need to carry it up stairs.
13. Regenerative Braking
Some e-bikes come with regenerative braking, which recovers some of the energy lost when braking and sends it back to the battery. This can slightly extend your range, but it’s more common in higher-end models.
14. Legal Speed Limit
In the UK, e-bikes are limited to a top assisted speed of 15.5 mph (25 km/h). This means the motor will stop providing assistance once you reach this speed, but you can still go faster using your own pedalling power.
15. Step-Through vs. Step-Over Frame
- Step-Through Frame: Designed for easy mounting and dismounting, ideal for commuters or riders with limited mobility.
- Step-Over Frame: Offers a more traditional bike design and is better for off-road or sporty rides.
