The manufacturer's figures, not ours.
This one carries 720 Wh of battery. The maker quotes 75 mi; in mixed riding with some hills, expect nearer 56 mi. A full charge costs about £0.20. Across a year that is roughly £984.00 less than making the same journeys by car, so the bike pays for itself in about 19 months. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

A legal fat-tyre bike with 55 Nm and turn signals
The ADO Oasis One runs 20 × 4 inch fat tyres with 55 Nm of torque and a taillight with integrated turn signals, at £1,549.
250W and 15.5 mph: it meets the EAPC rules, so there is no licence, no tax and no registration.
Fat tyres that stay within the rules
Most fat-tyre machines here are sold for private land, because the power needed to turn a four-inch tyre usually takes them past 250W.
- This one does it on 250W and 55 newton metres
- Seventy-five miles claimed, better than 85% of our catalogue
- A 48V 15Ah battery, five to six hours to charge
- And 331 lbs of payload on top of that
A lock-out suspension fork
Lock it on smooth tarmac, where an open fork dives at every pedal stroke and costs energy. Open it on the track.
On a bike that weighs 83 lbs and carries fat tyres, that switch is the difference between an efficient commute and a slow one.
Indicators in the taillight
ADO integrates turn signals into the rear LED rather than leaving them as an accessory.
You signal without letting go of the bars, which on an 83 lb bike matters more than on a light one. There is a front LED as well, and the display is a 2.4-inch IPS unit rated IPX7 for immersion rather than rain.
A torque sensor and Shimano 7-speed
A cadence sensor reads whether you are pedalling. A torque sensor reads how hard, so the assistance follows your effort rather than switching in as a block.
Three assist levels and seven gears to combine them with. ADO states that the CE version ships without a throttle, which is what makes the 250W rating meaningful.
Hydraulic brakes, and at 83 lbs they are necessary
Hydraulic rather than cable, on an aluminium frame and aluminium wheels.
One finger is enough, they do not fade on a long descent, and they keep their bite in the wet. Working range published as -10 to 40 °C, SGS CE certified.
Before the first ride, and who it is for
ADO sizes it for riders of 155 to 190 cm, with the saddle from 85 to 98 cm and a total length of 185 cm. Payload 331 lbs, net weight 37.5 kg.
- Fit the front wheel, the handlebars and the pedals, with two people
- Bed the hydraulic brakes in at walking pace
- Set the fork, and lock it out for smooth tarmac
- Run the tyres soft for grip, firmer for range
- Allow five to six hours for the first charge
Buy it if you want fat tyres and you want to ride on the road without a licence. That combination is rare, and this is the one in our range that does it properly.
