– Hub motor at 70 Nm torque with cadence sensing may cause jerky, less predictable power delivery on inclines, potentially impacting safety.
– Full-suspension setup (rear shock and lockout fork) with a non-integrated 720 Wh battery—solid capability but not up-to-date with frame-integrated batteries.
– 29” x 2.4” tyres and hydraulic disc brakes with 180 mm rotors, seven-speed Shimano drivetrain provide decent stopping power and versatility, but overall package trades off advanced motor control and weight distribution for affordability.
The Touroll U3 Pro is a new full-suspension electric mountain bike priced at just £776 / €889 when purchased directly from the official store. While considered quite affordable for a full-suspension model, the U3 Pro does come with certain limitations in its specifications. For instance, it is equipped with a hub motor offering a maximum torque of 70 Nm. Although hub motors can certainly be quite capable in theory, mid-drive systems are more common on electric mountain bikes, partly because they have a positive influence on a bike’s centre of gravity. As the advertising doesn’t mention a torque sensor, the bike likely relies on a cadence sensor. Especially on mountain bikes, motor control based solely on cadence can result in issues such as jerky power delivery – particularly noticeable when starting on inclines – which may lead to an unsafe riding experience.
Performance and Design Notes
The Touroll U3 Pro features a rear shock and a suspension fork with lockout functionality. Despite offering a decent capacity on paper, the 720 Wh battery isn’t integrated into the frame and thus not quite up to current standards – though this doesn’t have to be a deal-breaker for everyone. Deceleration is handled by hydraulic disc brakes paired with 180-mm rotors. A seven-speed Shimano derailleur manages gear shifts. Both the front and rear wheels are fitted with 29” x 2.4” tyres that appear to have a decent tread pattern.
