Description

X2 250W Electric Bike – Trekking Model with 500W Peak Power and Shimano Drivetrain

The X2 is a trekking-style electric bike with an aluminum frame and a Shimano 7-speed drivetrain, similar to the X3 but equipped with a slightly larger battery and a 500W peak power output for firmer acceleration. The motor has a rated power of 250W, staying within the European legal limit for use without extra restrictions on public roads.

250W Rated 500W Peak 48V 15Ah Shimano 7-Speed Front Suspension 26x1.95” Tires

The main difference from the X3 is battery capacity, slightly larger on the X2 (15Ah versus 13.5Ah), and the 500W peak power available for short bursts of acceleration or overcoming obstacles, while the continuous rated power stays at 250W per regulations.

Peak power and the practical benefit

The 500W peak power is available for short periods, such as starting from a standstill or sudden acceleration, without exceeding the legal continuous power limit of 250W. This setup offers a more dynamic pedaling response without compromising the bike's legal compliance.

Shimano drivetrain and front suspension

Like the X3, the 7-speed Shimano drivetrain allows active pedaling involvement, and the front suspension absorbs bumps for added comfort on mixed asphalt and gravel routes.

Recommendation: use peak power in moderation to protect long-term battery lifespan, especially during repeated acceleration cycles.

Who This Electric Bike Is Best Suited For

Urban Commuting with Quick Acceleration

The 500W peak power offers a firmer response when starting off in traffic.

Mixed Routes with Active Pedaling

The Shimano drivetrain allows active involvement, similar to an assisted traditional bike.

Comfort on Varied Roads

Front suspension reduces fatigue on medium distances over uneven asphalt or gravel.

Frequently Asked Questions about X2

What does 250W rated power and 500W peak power mean?

The 250W rated power is the sustained continuous output, compliant with EU regulations. The 500W peak power is available for short periods, such as during acceleration, without affecting the bike's legal compliance.

What's the difference between the X2 and X3?

The X2 has a slightly larger battery (15Ah versus 13.5Ah on the X3) and benefits from the explicitly stated 500W peak power. Both models use the same 250W rated motor and the same Shimano 7-speed drivetrain.

Is the bike legal on public roads without restrictions?

Yes, the 250W continuous rated power and assist limited to 25km/h place the X2 within EU regulations for electric bikes usable without registration or a special license.

What real-world range can I expect?

Range varies between 65 and 80km depending on rider weight, assist mode used and how often peak power is engaged.
