See UK LegislationYour Everyday Ride, Made Effortless
The Cyrusher Rumble 2.0 is the step-through electric bike that makes every journey feel easy, whether you're commuting to work, popping to the shops, or exploring the countryside. Its low-step frame lets you mount and dismount without a struggle, and the adjustable saddle suits riders from 5'1" to 6'2". With a 250W motor, 58-mile range, and 15.5 mph assisted speed, it's built for UK roads and ready for whatever your day brings.
Power That Keeps You Moving
Feel smooth, responsive acceleration from the 250W rear hub motor, which delivers up to 85 Nm of torque for confident hill climbing and quick getaways at traffic lights. It's fully compliant with UK e-bike regulations, so you can ride legally on roads and cycle paths. The motor pairs with a torque sensor for natural, intuitive pedal assist that responds to how hard you push.
Go Further on Every Charge
Travel up to 58 miles on a single charge, thanks to the 48V 18Ah battery. It's removable, so you can charge it indoors at home or at your desk, and a full charge takes just 6 to 7 hours. The battery is rated for 800 charge cycles, giving you years of dependable range for daily commutes and weekend adventures.
Comfort That Lasts All Day
The Rumble 2.0 smooths out rough city streets and gravel paths with its oil and spring suspension fork and 20" x 4" Chaoyang fat tires. The breathable ergonomic saddle and adjustable seat post help you find a riding position that's easy on your back and hips. With a step-through frame and stable wheelbase, every ride feels planted and controlled.
Stop Safely in Any Weather
Ride with confidence knowing the 180mm hydraulic disc brakes front and rear deliver strong, consistent stopping power, even in the rain. The integrated rear taillight brightens automatically when you brake, alerting drivers and cyclists behind you. A powerful LED headlight lights your way at dusk or dawn, so you're always visible on UK roads.
Stay in Control at a Glance
The 3.5" colour LCD display shows your speed, battery level, pedal assist mode, and trip distance in real time, and it's easy to read even in bright sunlight. The handlebar-mounted keypad lets you adjust assist levels and switch the headlight on or off without taking your hands off the grips. Shimano 7-speed gearing gives you the right gear for every hill and headwind.
Built Tough for Daily Life
The 6061 aluminium alloy frame with internal battery keeps the bike sleek and sturdy, while the integrated rear rack is ready for panniers or a basket. It carries up to 350 lbs, so you can haul groceries, work gear, or even a child seat. The 12-gauge stainless steel spokes and aluminium rims are built to handle potholes and kerbs without complaint.
