Samebike RS-A02 Pro Review: Fat Tyre Off-Road E-Bike Tested 2026

The Samebike RS-A02 Pro is one of the more interesting budget off-road e-bikes in the UK. It pairs chunky fat tyres with a folding frame, which is rare at this price. This review looks at what the published spec means for everyday riders.

We have not ridden this bike ourselves, but we have studied the manufacturer's figures, the UK e-bike rules and the real-world compromises buyers ask about. That is enough to judge whether the £749 asking price makes sense.

Samebike has built a reputation for affordable electric bikes. The RS-A02 Pro is its fat tyre folding model, aimed at riders who want one bike for trails, towpaths and town. Here is our honest take.

What is the Samebike RS-A02 Pro?

The RS-A02 Pro is a folding electric bike with wide 20 inch fat tyres. It is designed to handle soft ground and bad roads without rattling your hands off the bars. The folding frame is a bonus for storage.

Samebike sells this model as an off-road capable machine, but it is still a UK road legal e-bike. That means it assists up to 15.5 mph, and the motor is limited to 250W. It is not a speed pedelec.

The frame is aluminium, the brakes are mechanical disc, and the battery sits behind the seat tube. All the parts are standard, so replacement is easy. You will not find hydraulic brakes or a mid-drive motor at this price.

Where it fits in the range

The RS-A02 Pro is one of the larger 20 inch folders in the Folding Bikes category. It shares a platform with other Samebike models but adds the fat tyre package. That makes it a little taller and heavier.

If you already own a standard city folder, the RS-A02 Pro will feel much softer over bumps. The fat tyres do most of the suspension work, so the front fork is only there for bigger hits.

What you get for £749

At Biktron, the Samebike RS-A02 Pro Fat Tire Off Road Ebike is £749, reduced from a recommended price of £1229. That discount makes it one of the cheapest fat tyre folders in the UK.

For that money you get a folding 20 inch e-bike, a rear hub motor, mechanical disc brakes, a basic suspension fork and a removable battery. Some rivals at this price skip the disc brakes or use cheaper folding joints.

The bike arrives partly assembled. Most buyers need to fit the handlebars, pedals and front wheel. If you are not confident, a local bike shop can build it for about £50.

The warranty terms are standard for the industry. The battery and motor have their own cover, and the frame is covered against manufacturing defects. Keep your proof of purchase.

What we would upgrade first

The first upgrade we would suggest is a pair of better brake pads. Mechanical disc brakes work fine, but cheap pads wear quickly on a heavy e-bike. A suspension seatpost also helps, because the rear end is rigid.

A set of puncture-resistant inner tubes is worth the extra £15. Fat tyres are harder to remove at the roadside, so avoiding flats matters more than on a skinny commuter.

Motor, battery and real-world range

The RS-A02 Pro uses a rear hub motor, which is the simplest and quietest setup for a budget folder. It pushes from the back wheel, so it feels natural when you pedal with the assist on.

Any UK e-bike on the road must stop assisting at 15.5 mph, and the motor output must stay at 250W or less. You can ride faster, but only with your legs. The motor is not a throttle on this model, it is pedal assist.

Range is the number buyers worry about most. Samebike publishes a figure for this model, but no lab test matches a windy hill. Treat the quoted range as a best-case number on flat ground with low assist.

In cold weather, expect about a third less range. Heavy riders on soft tyres will also see the battery drain faster. If your round trip is 20 miles, this bike should cope. If it is 35 miles, plan a charge at work.

How to extend the battery life

• Keep the tyres pumped to the higher end of their range for road riding.
• Use the lower assist level on flat ground and save the highest for hills.
• Store the battery indoors in winter, because cold cells lose capacity.
• Charge it to 80 percent for daily use, and full only for long rides.

Off-road handling and fat tyres

Fat tyres are the headline feature. The wide 20 inch tyres spread your weight over a bigger contact patch. That gives grip on mud, sand and loose gravel, and it cushions rough trails better than any fork at this price.

The trade-off is rolling resistance. Fat tyres are slower on tarmac and louder than a 28 inch commuter tyre. They also make the bike heavier to carry when folded. If most of your riding is smooth tarmac, these tyres are overkill.

The RS-A02 Pro is not a full suspension mountain bike. The front fork takes the sting out of kerbs and roots, but the rear stays rigid. For canal paths and forest fire roads, that is fine. For rock gardens, you want a bigger travel bike.

The tyres come from a budget brand, so check the sidewalls for cuts after rocky rides. Replacing a fat tyre costs about £40, which is worth knowing before you ride over glass.

Tyre pressure advice

• For road and hardpack, run them near the maximum pressure printed on the sidewall.
• For sand or mud, drop pressure to about 15 to 20 psi for more grip.
• Never ride them completely soft, because the tyre can roll off the rim.

UK e-bike law: is it road legal?

In the UK, an electric bike must meet EAPC rules to be ridden without a licence. The motor must be 250W or less, assist must cut off at 15.5 mph, and riders must be 14 or over. The government's electric bike rules confirm these limits.

If an e-bike exceeds them, it becomes a moped. That means registration, insurance, a number plate and a motorcycle helmet. The RS-A02 Pro is sold as a road-legal EAPC, so it should meet those rules out of the box.

The Sustrans guide to e-bike law explains that you can ride an EAPC on cycle paths and roads, but not on footpaths unless the local authority allows cycling. Always check the signs.

The Cycling UK e-bike guide also covers battery care and safe riding. Some riders derestrict e-bikes for more speed on private land. That is not legal on UK roads, and it also voids the warranty and drains the battery faster.

Where you can ride

You can ride the RS-A02 Pro on roads, cycle lanes, bridleways and byways where cycling is allowed. You cannot ride it on public footpaths unless it is a shared use path. Off-road on private land, ask the landowner first.

Folding and portability

The RS-A02 Pro folds in the middle, and the pedals fold too. That makes it easier to store in a flat, a car boot or a train luggage area. It is not a light bike, but the fold is simple and quick.

Fat tyre folders are heavier than skinny folders. Expect to lift around 25 to 30kg when folded, depending on the battery. That is fine for short carries but not for lugging up three flights of stairs daily.

The folding joints need a quick check before every ride. Keep the hinges clean and the bolts tight. A loose hinge is dangerous on a bike with this much mass, especially over bumps.

The handlebar stem also folds, which helps the bike fit into smaller cars. The battery is removable, so you can take it inside to charge, which reduces the weight you lift by a couple of kilos.

Is it right for commuters?

If you have a short commute with rough roads or park paths, the RS-A02 Pro is a comfortable choice. If you need to carry a folded bike onto a busy train every day, its weight may become a chore.

Samebike RS-A02 Pro vs other Biktron e-bikes

The RS-A02 Pro sits in the middle of the All Bikes line-up. It costs more than the commuter-focused SAMEBIKE RS-A01 Pro but adds fat tyres and a taller stance for rough ground.

If you want a similar ride with a different look, the Samebike LO26 Plus is £849. It has a rear rack and slightly different geometry. The RS-A02 Pro is the cheaper pick if you do not need the rack.

For pure road commuting, a City Bikes model with thinner tyres will be faster and lighter. But it will not handle towpaths or wet leaves as well. The fat tyres are the point of the RS-A02 Pro.

Which Samebike fat tyre model?

If your rides are mostly off-road and you want a folding frame, the RS-A02 Pro is the one to choose. The LO26 Plus is better for carrying luggage. The Mountain Bikes category has non-folding options if portability does not matter.

Verdict: should you buy it?

The Samebike RS-A02 Pro is a good value off-road folder at £749. It is not a high-end mountain bike, and the fat tyres cost you speed and weight. But for relaxed trail rides and potholed commutes, it is a confident choice.

The main weaknesses are the basic suspension and the weight. If you need a bike to carry upstairs every day, look at a lighter folder. If you want a do-it-all machine for weekends, this is worth a look.

The fat tyres give it a planted feel that cheaper city bikes lack. Combine that with the fold and the price, and it is one of the easier off-road e-bikes to recommend for UK beginners.
