The BULLS Lacuba EVO E45 is a fast trekking e-bike built for riders who want to cover serious distance at pace. At its heart sits a quiet Brose mid-drive delivering 350W (530W peak) and a hefty 90Nm of torque, paired with a removable BMZ 37V 17.5Ah battery of roughly 648Wh. That combination supports assistance up to 28 mph (45 km/h) and a real-world range of around 50 to 130 miles depending on the level of support you select.
Componentry is genuinely premium for the category: a 20-speed Shimano XT / GRX Di2 setup handles shifting, Tektro Dorado hydraulic disc brakes with 203mm rotors provide confident stopping, and puncture-resistant Schwalbe Energizer Plus tyres roll on 28in wheels. The 7005 aluminium frame comes in five sizes with both high-step and step-thru options.
Important: as a 45 km/h speed pedelec exceeding the 250W / 25 km/h limit, this bike is not a UK road-legal EAPC and is intended for off-road or appropriately registered use.

- High-step and step-thru frames across five sizes
A Closer Look at the Bulls Lacuba EVO E45
The Brose mid-drive at the heart of the Lacuba EVO E45 is notably quiet in operation compared with many rival motors, and its 90Nm of torque combined with a 350W nominal (530W peak) rating is what makes 45km/h (28mph) assisted riding genuinely usable rather than a headline figure. The removable BMZ battery, at roughly 648Wh, is large even by speed-pedelec standards, supporting a real-world range Bulls quotes at around 50 to 130 miles depending on how much assistance you use.
Componentry is set up to match the performance: 20-speed Shimano XT / GRX Di2 electronic shifting removes cable-adjustment maintenance almost entirely, and Tektro Dorado hydraulic brakes with 203mm rotors are sized to haul the bike down from higher speeds repeatedly and predictably.
Who Rides the Lacuba EVO E45, and Where
This is a bike for riders covering serious daily distance — intercity commuters, or anyone who currently drives a journey that cycling could realistically replace if it didn’t take so long at 15.5mph. As a 45km/h speed pedelec, it exceeds the UK’s 250W / 25km/h EAPC limit and is not a road-legal EAPC: UK law requires DVLA registration, insurance and an approved helmet to ride it on the road, or it can be used off-road on private land without those requirements.
Setup & Care
Brose’s own instruction manual (downloadable below) covers the motor’s service intervals and diagnostics in detail. Di2 electronic shifting needs periodic firmware and battery-level checks rather than cable tension adjustments, and Tektro’s 203mm rotors should be bedded in gradually. Given the higher assisted speed, check tyre pressure and tread wear more often than on a standard-speed e-bike, and store the BMZ battery at a partial charge if the bike won’t be ridden for extended periods.
