This Model Is Fully Compliant With UK Road Regulations

This bike is built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning it can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h).

Powerful and intuitive electric assistance

Enjoy a responsive ride with the ANANDA 250W motor, which delivers smooth, consistent power to help you tackle everyday journeys. The torque sensor reads your pedalling effort instantly, so the motor boosts you in a way that feels completely natural and controlled. Whether you're setting off from traffic lights or climbing a gentle incline, the assistance blends seamlessly with your own input.

You can travel up to 15.5 mph with assistance, perfectly aligned with UK e-bike regulations. The 36V 18.2Ah battery gives you a generous range of up to 75 miles on a single charge, so you can commute, run errands, or explore country lanes without worrying about running out of juice. A colour Bluetooth display keeps all your ride stats clear and easy to read, while the Shimano 7-speed gears let you find the ideal cadence for any situation.

Built for comfort and everyday practicality

The step-through aluminium frame makes mounting and dismounting effortless, even when you're wearing everyday clothes. With a rider height range of 5ft 3in to 6ft 7in, the OT05 fits a wide range of cyclists, and the saddle adjusts from 28 to 36 inches off the ground for a tailored riding position. The front suspension fork smooths out potholes and uneven tarmac, while the 27.5 x 2.25-inch pneumatic tyres provide a cushioned, grippy ride on UK roads.

Stopping is confident in all weathers thanks to the hydraulic disc brakes, which offer precise, low-effort control. The bike comes fully equipped with mudguards, a rear rack, integrated lights, and a USB charging port, so you're ready for the daily commute or a weekend shop straight out of the box. At 61.7 lbs, it's substantial but manageable, and the IPX5 water resistance means you can ride through typical British drizzle without concern.

Effortless power for daily journeys

The 250W brushless geared motor from ANANDA delivers dependable, quiet assistance that makes light work of your daily trips. It's tuned to provide a natural-feeling boost, helping you maintain a steady pace without breaking a sweat, whether you're heading to the office or popping to the shops. The motor supports a top assisted speed of 15.5 mph, keeping you within UK e-bike law while still making good progress through town.

Because the motor responds to your pedalling via a torque sensor, the power delivery is smooth and predictable, never jerky or overwhelming. This means you can enjoy a more connected, bicycle-like experience that simply flattens the hills and shortens the miles.

Rides like a bike, just easier

The torque sensor is the heart of the OT05's refined ride feel. It measures how hard you're pushing on the pedals and adjusts the motor's output instantly, so the assistance feels like a natural extension of your own strength. This gives you a smooth, linear power delivery that's almost imperceptible, avoiding the on-off surge you might get with simpler cadence sensors.

On hills, the sensor ramps up help in real time, preventing you from losing momentum, while on descents or when you ease off, it reduces power to keep you in full control. This intelligent response not only makes riding more enjoyable but also enhances safety by preventing unexpected acceleration, so you can focus on the road ahead.

The high‑capacity 36 V 18.2 Ah battery gives you a genuine range of up to 75 miles, so you can plan longer routes with confidence. Whether it’s a weekend tour along the South Downs or a daily commute across London, this e‑bike keeps you moving. Enjoy the freedom to ride further, knowing your battery is built for endurance.

Stop with confidence in all conditions

Ride with peace of mind, even on wet British roads. The hydraulic disc brakes deliver consistent, powerful stopping performance whenever you need it, from a gentle slow‑down to an emergency stop. You’ll feel the immediate, controlled response through the levers, giving you extra safety on busy roundabouts or steep descents. It’s not just about stopping — it’s about staying in control and enjoying every mile.

Stay informed at a glance

Keep your focus on the road ahead while staying fully aware of your ride. The clear LCD display shows your current speed, distance travelled, battery level, and more, all in real time. It’s easy to read in bright sunlight or under grey skies, so you can adjust your effort or plan a charge stop without fuss. This smart feature makes every journey smoother and more enjoyable.

Be seen, day and night

Ride safely through dim mornings and dark winter evenings with the integrated lighting system. A bright front headlight illuminates the path ahead, while the rear light with reflectors makes sure you’re visible to traffic from behind. It’s all powered by the bike’s battery, so you never need to worry about separate batteries. Stay safe and seen on every UK road, whatever the hour.

Ready for everyday journeys

Enjoy a smooth, comfortable ride on 27.5-inch tyres that soak up bumps on UK roads and cycle paths. The bike comes with full-length mudguards already fitted, so you stay clean and dry when the weather turns, and a sturdy rear rack makes carrying shopping or a pannier effortless.

Taking the front wheel off for storage or transport is quick and simple thanks to the quick-release system – ideal if you need to pop it in the boot of a car or tuck it away in a hallway. It’s all about making your daily trips practical and hassle-free, whether you’re commuting to work or nipping to the shops.
