This Bike Is Not Road Legal. Private Land Use Only.
This bike cannot be ridden on public roads, pavements, or cycle paths in the UK. Its motor output and assisted top speed exceed the legal limits set by the UK Electrically Assisted Pedal Cycle (EAPC) regulations, which cap electric bikes at 250W motor power and 15.5 mph (25 km/h). Because this bike exceeds both thresholds, it is classified as a motor vehicle and would require registration, insurance, and a valid licence to use on public roads. This bike is designed exclusively for use on private land such as farms, estates, and off-road tracks where road traffic law does not apply.
See UK LegislationYour all-terrain companion for British adventures
The Allegro TDL6131 is built for riders who want one bike that can handle the daily commute, a weekend tour, and a blast along forest trails. With a 750W motor, 62 miles of range, and full suspension, it takes the effort out of every ride. Whether you are dodging potholes on city streets or exploring bridleways, this e-bike delivers dependable power and comfort.

Powerful 750W motor for steep climbs
You will tackle hills with confidence thanks to the 750W brushless rear hub motor, which peaks at 1000W for strong acceleration. It is paired with a 48V system to give you smooth, responsive assistance up to 31.1 mph. The motor is quiet and efficient, so you can enjoy the ride without excessive noise.

Ride up to 62 miles on one charge
The 25Ah battery gives you a real-world range of 62 miles, so you can commute all week or explore the countryside without range anxiety. Charging takes just 5 hours, so you can top up overnight or during the working day. The battery is integrated into the frame for a clean look and better protection from the elements.

Full suspension and fat tyres for comfort
Rough roads and gravel paths feel smoother thanks to the front hydraulic fork and rear shock absorber. The 27.5-inch by 3.0-inch Kenda fat tyres add extra cushioning and grip, helping you stay in control on loose or uneven surfaces. Even on long rides, the upright riding position and padded saddle keep you comfortable.

Hydraulic disc brakes with motor cut-off
You can stop quickly and safely in wet or dry conditions with the front and rear hydraulic disc brakes. The brake levers automatically cut power to the motor when you pull them, giving you an extra layer of safety. This is especially useful on steep descents or in busy traffic.

Clear display and easy controls
The LCD screen shows your speed, battery level, and pedal-assist mode at a glance, so you always know what is happening. You can switch between pedal assist and throttle mode to match your effort level. The controls are within easy reach, letting you adjust settings without taking your eyes off the road.

Strong foldable frame for everyday use
The aluminium alloy frame is both lightweight and sturdy, with a maximum load capacity of 220 lbs. It folds down for easier storage in a flat, garage, or car boot. The Shimano 6-speed or 7-speed gears give you the right ratio for any terrain, from city streets to steep hills.
