Is the FLXS legal?
Yes. The FLXS only assists you if you pedal yourself and stops at 25 km/h, with a 250W motor and no throttle. This makes it just an electric bike, not a moped. So you are allowed to ride it anywhere you can ride a regular bike.
How fast does the FLXS go, and am I allowed to increase its speed?
The FLXS supports speeds up to 25 km/h. Faster is not allowed: once you modify a fatbike to go faster, it is legally considered a moped. You are then required to have insurance, a license plate, and a helmet, and your warranty becomes void. With our bikes, you ride safely within the rules.
Do I need a driver's license, insurance, or registration for the FLXS?
No. Because the FLXS supports up to 25 km/h, it counts as a regular bike. No driver's license, no license plate, no mandatory insurance. A bike insurance against theft or damage is smart, but that’s up to you.
From what age are you allowed to ride the FLXS?
In the UK you must be 14 or over to ride an electric bike (EAPC) like this one on public roads (gov.uk). A helmet is not compulsory for EAPC riders, but it is recommended.
What warranty do I get on the FLXS?
You get a 2-year warranty on the frame and 1 year on the moving parts. If something breaks during that period due to a manufacturing defect, we will take care of it for you.

Phatfour FLXS at GOfatbike

The Phatfour FLXS is a compact electric fatbike, designed for the city. Popular with those looking for a bike that is agile and easy to park, without compromising on comfort. You sit comfortably, the motor assists as soon as you pedal, and the wide Schwalbe tires provide a stable, smooth feeling on the road. The compact size makes the FLXS handy in busy streets and tight spots. In this explanation, we’ll go through what the FLXS can do, its strengths, and what to consider before choosing.

Compact size and comfort

The first thing you notice is how manageable the FLXS is. It’s more compact than many other fatbikes, making it more agile and easier to store in tight spaces. Despite its compact size, you sit comfortably with a pleasant, upright posture. The bike comes ready to ride and is easy to assemble, so you can get going quickly. If you’re looking for a large, heavy bike for long rides outside the city, this isn’t your model. It’s perfect for short, daily trips.

Range and battery

The FLXS has a removable battery, which is convenient for daily use. You take it out to charge indoors, and with a second battery on hand, you can extend your range without waiting for the charger. How far you go on a charge depends on your weight, the wind, the number of stops, and the level of assistance you choose. So, expect a range rather than a fixed number. For city rides, you’ll get a good distance, and when the battery runs out, you simply swap or recharge it.

Motor, speed, and regulations

The motor assists you up to 25 km/h and then cuts out, so you always pedal yourself. There is no throttle. This means the FLXS counts as a regular electric bike, and you don’t need a license, registration, or helmet. That makes it very accessible: just hop on and ride. If you want to tune the bike to go faster, we advise against it. Doing so takes it out of the legal category, the brakes and frame aren’t designed for it, and you lose your warranty. It rides best within the legal limits.

Tires, brakes, and riding feel

The wide Schwalbe tires are a strong point. They provide grip and hold the line, on asphalt as well as rougher surfaces, and they absorb some of the vibrations. The ride feels calm and stable, exactly what you want in busy traffic. The brakes bring you to a controlled stop, even on wet roads. The whole setup feels solid and predictable, without becoming twitchy during a quick stop. This keeps the bike well under control.

Who is this fatbike for

The FLXS suits those who live in the city and want a bike that moves easily through daily traffic. The compact size is great for tight parking, and the bike is compatible with various accessories so you can customize it as you like. If you mostly ride short, daily trips, this is a good choice. It’s less suitable if you want a large bike for long rides or lots of cargo. Compact is an advantage in the city but can be a limitation outside it.
