Electric Bike Performance & Range Overview

October 6, 2025

This document summarizes real-world performance expectations for a range of popular electric bikes, found on Ride Electric Bike focusing on range, speed, and battery behavior under different riding conditions. It compares claimed manufacturer specifications with realistic estimates based on terrain, rider weight, weather, and typical urban/suburban usage.

Engwe Engine Pro	48 V × 16 Ah	75 km	50–60 km	45 km/h	40 km/h	Efficient under throttle control; sensitive to headwinds.
Velowave Ranger	48 V × 15 Ah	55 miles	35–45 miles	28 mph	26 mph	Excellent hill control; mid-range power output.
Cyberbike M2	52 V × 20 Ah	70 miles	40–55 miles	32 mph	30 mph	Smooth acceleration; long-lasting mid-range torque.
Askmy A1	48 V × 20 Ah	65 miles	40–50 miles	31 mph	28 mph	Performs best under pedal assist mode.
Luckeep LK7	48 V × 20 Ah	60 miles	40 miles	31 mph	28 mph	Range efficiency declines at higher throttle use.

⚙️ Performance Insights

1. How Far Each Bike Goes per Charge

Claimed ranges are often measured in Pedal Assist 1–2, flat ground, no wind, and light load.
In mixed real-world use, expect 20–30% less range on average.
High-voltage bikes (like the G300 Pro or EKX X21 MAX) can hold speed better but consume energy faster.

2. Top Speed on Flat Roads

Most mid-power e-bikes reach 28–32 mph.
High-output models like HappyRun G300 Pro and EKX X21 MAX can exceed 45 mph, though sustained operation at these speeds significantly reduces range.

3. Speed Retention on Uphill Sections

Dual-motor setups (Amyet S8, Bluvall B1) maintain better torque and speed on inclines.
Single-motor models typically lose 15–25% speed on steep grades.

4. Climbing Capability

Most commuter e-bikes handle 15–20° slopes comfortably.
The Amyet S8 and HappyRun G300 Pro are capable of tackling slopes up to 30–35° with moderate loads.

5. Effect of Pedaling on Range

Pedal assist can extend range by 20–40% depending on effort.
On large dual-motor models, light pedaling mainly helps with acceleration and hill starts rather than total distance.

6. Range Reduction in Cold Weather

Lithium-ion batteries lose capacity in low temperatures.
Expect a 15–25% drop at 0–10 °C and up to 35% below freezing.

7. Realistic Range vs Claimed Specs

Marketing figures assume ideal conditions.
Actual results depend on:

Average speed
Total rider/cargo weight
Terrain and incline
Wind resistance
Tire pressure and type

8. Speed vs Range Relationship

Energy draw increases exponentially with speed.
At 50 mph, power usage can be double that of 30 mph, cutting range by nearly half.

9. Headwinds and Cargo Weight

A 10 mph headwind or 20 kg cargo can reduce range by 10–20%.
Large, upright bikes experience more drag than compact step-through designs.

🔋 Battery Planning for a 50 km Commute

Let’s estimate power needs for a 50 km daily round trip:

Usage Factor	Energy Consumption	Battery Capacity Required
Light assist, flat terrain	~15 Wh/km	750 Wh
Mixed terrain, some hills	~20 Wh/km	1,000 Wh
High speed, heavy load	~25 Wh/km	1,250 Wh+

Interpretation:

For 50 km total travel, a 1,000–1,200 Wh battery (≈ 48 V × 21–25 Ah) is sufficient.
To ride 100 km total per day, aim for at least 2,400 Wh (72 V × 30 Ah).

✅ Recommendations

Best for Long Range: HappyRun G300 Pro — large 72 V × 30 Ah battery, strong hill climbing, highest energy reserve.
Best for Balanced Commuting: Amyet S8 — efficient dual motor, solid range, smooth acceleration.
Best for Value: Bluvall B1 — practical mix of performance and affordability.
Best for Speed Enthusiasts: EKX X21 MAX — extreme top speed, but trade-off in efficiency.

For colder climates or heavier loads, consider a bike with at least 20% higher battery capacity than the minimum calculated for your commute.
