The JOROTO X4S is a magnetic-resistance indoor cycling bike with a belt drive, two flywheels and a stated maximum user weight of 150 kg, priced around £399.99 (checked Oct 2026). JOROTO's page also gives a rider height range of 150-195 cm and a one-year warranty.
This review rests on the maker's published specification, not on use of the bike, and notes where the page contradicts itself.
What JOROTO says the X4S is
JOROTO describes a Bluetooth exercise bike with a multi-groove silent belt drive at a 4.29:1 ratio, six magnets for resistance and an emergency leather brake pad. The monitor is backlit and shows time, distance, speed, RPM, resistance, calories and heart rate when a Bluetooth band is connected. The bike uses the iConsole Bluetooth protocol and is battery powered.
Who the specification suits
The figures suit riders who need a high stated weight limit, who fall in the stated height range, and who want an indoor-cycling posture with a seat and handlebar that adjust in four directions. Anyone below 150 cm or above 195 cm is outside the maker's stated range. Because the console runs on batteries, placement is not tied to a wall socket.

What is the maximum user weight of the JOROTO X4S?
JOROTO lists a maximum user weight of 150 kg (about 330 lb) and a suitable rider height of 150-195 cm.
That is the highest stated limit of the four bikes on this site, against 125 kg for the ProForm 225 CSX, 120 kg for the Hop-Sport and 113 kg for the Schwinn IC3.5. A limit is the maker's ceiling, so leave margin and read the manual. The height range and the inseam range (71-95 cm) are the only published rider-fit ranges among the four bikes, which makes it possible to check fit from a tape measure before ordering.
Is the resistance controlled by an app?
No. The page describes six magnets and a manual resistance setting, with the monitor showing the resistance level, and it does not describe app-controlled resistance.
That means app content can be followed, since the bike uses the iConsole Bluetooth protocol and the page mentions a Kinomap trial, but the rider sets the resistance by knob. The page gives the Kinomap trial as 30 days in one place and 44 in another, so confirm what is included. For app-driven electronic resistance, see the Schwinn IC3.5 review.
Does the JOROTO X4S need mains power?
No. JOROTO lists the bike as battery powered.
Reasoning from that, the bike can stand anywhere with floor space, which helps in a spare room without a nearby socket, at the cost of keeping batteries in the console. The page lists only "battery powered" and gives no battery type, number or life, so ask the seller what the console takes.
What warranty does the X4S have?
JOROTO lists a one-year warranty with one year of free replacement parts. Check how claims work for UK buyers with the seller.
The page is JOROTO's EU store and quotes euro prices, so the UK retailer's terms are the ones that apply to a UK purchase. GOV.UK guidance for sellers says an item that is faulty, not as described or does not do what it is supposed to must be refunded, and that an item returned within 6 months must be repaired or replaced. A retailer can explain how that applies, alongside the maker's one year.
How big is the JOROTO X4S?
JOROTO lists an assembled footprint of 52 x 126 cm. Its weight is given as 44 kg in one table and 42.5 kg in another, so confirm with the seller.
A footprint of about 126 x 52 cm and a weight in the low 40s of kilograms mean this is a larger, heavier bike than a basic upright such as the Hop-Sport HS-010H Rio. Dual flywheels and a belt drive are mechanical features the maker lists, and the page calls the belt drive silent, but it gives no noise measurement. See the noise guide and flooring guide for planning.
Where the page contradicts itself
Several figures differ between sections of the same page, so treat them with caution and confirm with the seller. Net weight is listed as 44 kg in one table and 42.5 kg in another. The flywheel is described variously as 11.5 kg of cast iron plus a lighter aluminium wheel and as 13 kg in total. Seat fore and aft adjustment is 6 cm in one place and 12 cm in another. Customer support hours are listed as 24/7 and as weekdays 9am to 6pm, and the Kinomap trial is given as 30 and 44 days. The page also does not publish a pedal specification.
What to check before buying
- Which figures are right. Ask the seller to confirm weight and flywheel figures if they matter for moving or placing the bike.
- Pedals. No pedal type is published, so check if you plan to use cycling shoes.
- Warranty. JOROTO lists one year and one year of replacement parts. Check how a claim works for UK buyers.
- Assembly. The package includes tools and a manual, and some small parts may be packed separately.
- Apps. The page mentions a Kinomap subscription trial whose length varies on the page.
- Currency. The page quotes euro prices; use the UK retailer's price.
Who should skip the JOROTO X4S
Riders under 150 cm or over 195 cm are outside the stated height range. Anyone who wants resistance controlled automatically by an app should look at the Schwinn. Buyers who need a published pedal specification, consistent weight figures or a tight budget may prefer another option; the under £300 guide covers lower-priced bikes.
How it compares on the numbers
| Bike | Max user weight | Resistance | Power | Indicative price |
|---|---|---|---|---|
| JOROTO X4S | 150 kg | Magnetic, 6 magnets, knob | Batteries | Around £399.99 (checked Oct 2026) |
| ProForm 225 CSX | 125 kg | 20 digital levels, magnetic | Not published | Check retailer |
| Hop-Sport HS-010H Rio | 120 kg | Mechanical knob | Batteries (not included) | Around £93.99 (checked Oct 2026) |
| Schwinn IC3.5 | 113 kg | 50 levels, 0-100 | Wall adapter | Check retailer |
The X4S has the highest stated user weight, the only published rider height range and the only belt drive ratio. The page also describes an emergency brake pad, a Q-factor of 195 mm and Bluetooth heart-rate support from bands that are not included. The Q-factor is the distance between the pedal mounting points, which the maker lists but does not explain. None of these figures is a measure of ride quality, and no ride-quality claim is made here.
Alternatives
For an app-connected indoor cycling bike with electronic resistance and a 113 kg limit, see the Schwinn IC3.5 review. For an upright bike with digital levels, see the ProForm 225 CSX review. All four bikes are compared in the home exercise bike guide.
Price context
The indicative UK price is around £399.99 (checked Oct 2026), which is the highest of the confirmed prices among the bikes on this site, ahead of the Hop-Sport at around £93.99. Prices move, so check the current figure. The NHS lists riding a bike as moderate activity; ask a health professional before starting if you have a medical condition.
