As electric bikes continue to surge in popularity across the UK, more riders are skipping factory-built models in favour of high-powered electric bike conversion kits. Among these, the 2000W electric bike kit stands out as one of the most sought-after choices in 2025 for good reason.
A 2000W e-bike motor offers the perfect balance of power, speed, and reliability. It’s ideal for a wide range of riders from daily commuters who need to cover longer distances quickly, to off-road adventurers who demand torque and control on rough terrain.
- It delivers fast top speeds of up to 60 km/h, ideal for private land or trail use.
- It climbs hills and inclines with ease, no more struggling on steep roads.
- Paired with the right battery, it offers a 40–80km+ range, meaning fewer charging stops.
Whether you're upgrading your old mountain bike or building a custom long-range commuter, a 2000W electric bike conversion kit with battery gives you more freedom, more power, and more value all while staying flexible and upgradable.
What to Look For in a 2000W Electric Bike Kit
Choosing the right 2000W electric bike kit with battery can significantly impact your riding experience especially when performance, legality, and ease of installation matter. Here's what UK riders should evaluate before buying:
Motor Type: Hub vs. Mid-Drive
Most 2000W e-bike kits use powerful hub motors due to their durability and lower maintenance. Hub motors are great for high-speed riding and are easier to install than mid-drive systems. However, mid-drives offer better torque for hill climbing but come at a higher cost and more complex setup.
- Flat and mixed terrains
- Simpler DIY conversions
- Riders who prioritize speed and affordability
- Battery Pairing: 52V vs. 60V vs. 72V
Voltage determines how much power your motor can draw. Pairing your 2000W electric bike kit with the right battery is essential:
- 52V: Balanced performance and range great for commuting.
- 60V: More punch and higher top speed ideal for sporty riding.
- 72V: Maximum torque and acceleration designed for off-road dominance.
Always ensure the battery and controller are matched to the motor to avoid performance or safety issues.
Speed & Range Expectations
A well-matched 2000W kit can reach speeds of 50–60 km/h (30–37 MPH), depending on your setup and terrain. Paired with a quality battery (e.g., 52V 20Ah or 30Ah), expect a range of 40–80 km per charge.
Legal Considerations in the UK
- Limited to 250W
- Have a top speed of 25km/h (15.5 MPH)
- Operate with pedal assist only (no throttle)
Many 2000W kits, like KirbEbike’s, offer a legal mode that limits output for compliance. Always check if your kit includes this feature if you plan to ride on public roads.
Installation & Compatibility
- Wheel size (20", 26", 27.5", 29", 700C, etc.)
- Dropout width (standard or fat tire)
- Freewheel or cassette options (7-speed thread vs. 8s/9s/10s cassette)
Included Accessories
Premium electric bike conversion kits (2000W) come with valuable add-ons like:
- LCD displays (e.g., S6, LCD8)
- Thumb throttle or twist throttle
- Pedal Assist Sensor (PAS)
- Waterproof cable harness
- Electric brake levers
Top 3 Kits: Power, Performance, and Value
If you're looking to convert your bike into a high-performance machine, these 2000W electric bike conversion kits with battery offer the best blend of speed, range, and reliability for UK riders in 2025:
1. KirbEbike’s 52V 2000W MTX Rim Kit
Best All-Around 2000W Kit for UK Riders
A perfect balance of power, range, and price, the KirbEbike 2000W kit is ideal for daily riders who want a serious performance upgrade.
- Max Speed: 50–60 km/h
- Est. Range: 40–80 km (based on terrain & battery size)
- Voltage: 52V
- Motor Power: 2000W direct-drive brushless hub motor
- Compatible Wheel Sizes: 26", 27.5", 28", 29", 700C

- Optional UK-legal 250W mode (25km/h limit via display)
Why It Stands Out:
This kit hits the sweet spot for most UK riders offering strong hill-climbing torque, customizable battery options, and support for multiple wheel setups. Whether you're commuting or cruising backroads, the MTX 2000W is built to perform.
2. KirbEbike’s 1500W–2000W Fat Tire Ebike Kit
Best for Off-Road & Fat Bike Riders
Designed specifically for rugged conditions, this 2000W electric bike conversion kit with battery is a powerhouse built for fat tire bikes perfect for sand, snow, or rough terrain.

- Max Speed: 50–60 km/h
- Est. Range: 40–80 km
- Voltage: 52V
-
Compatible Wheel Sizes:
- 20" × 4.0" (175mm or 190mm dropout)
- 26" × 4.0" (175mm or 190mm dropout)
-
Battery Options:

- 1T4 waterproof cable harness
- Electric brake levers
- Thumb throttle
- 250W mode via display (UK road-legal toggle)
Why It Stands Out:
This fat tire kit uses the same powerful motor as the standard MTX model but is optimized for wide, heavy-duty wheels. Whether you're hitting beach trails or snowy hills, the KirbEbike Fat Tire Kit delivers power and stability where it counts.
3. Dastrad 2000W MTX Kit
A Solid 2000W Performer:
The Dastrad 2000W MTX Kit is another powerful 2000W electric bike conversion kit option for riders focused on speed and reliability. While it doesn’t include a battery, it still ranks as a strong alternative for DIY enthusiasts.
- Motor Power: 2000W rear hub motor
- Voltage: Typically paired with 52V battery (sold separately)
- Speed Potential: Up to 60 km/h (varies by battery)
- Battery: Not included (must purchase separately)
- Wheel Compatibility: Fewer sizes than KirbEbike (mostly standard 26", 28", 700C)

Why It Stands Out:
For experienced DIYers or riders with their own batteries, Dastrad offers a respectable 2000W kit at a competitive price point. However, limited wheel compatibility and no included battery may be a downside for first-time converters.
