UMIT Bikes 2026: A Complete Guide to Mountain, BMX and Leisure Bikes by Age and Price

This week Híper Ocio received a batch of UMIT bikes we have not had in the shop before: adult mountain bikes with 27.5" and 29" wheels and hydraulic disc brakes, a street BMX, a children's bike with wide fat-bike-style tyres and several small sizes with a basket for the little ones. Many of you will already know the brand, as it is also sold at Decathlon and Carrefour, but until now at Híper Ocio we had focused mainly on Toimsa for character-licensed bikes with stabilisers. UMIT covers different ground: boys and girls who already pedal confidently, and adults who want a proper mountain bike without paying specialist-shop prices.

As with any bike, size and real-world use matter more than the brand. That is why this guide will not simply list the whole catalogue: it explains which UMIT model makes sense depending on age, height and what the bike will be used for, with the prices and the real stock we have right now at our shop in Albox.

If you already know your children's bike sizes and just want to see the full catalogue, the UMIT adult and mountain bike collection, 24-29" is on the website. If not, keep reading.

Who UMIT are and how they differ from what we already sold

UMIT is a European bike brand focused on the mid-range: aluminium frames on most of its adult and junior models, Shimano gears on its mountain bikes, and a catalogue that runs from a first bike with stabilisers up to mountain bikes with 21 and 24 speeds. This is not top-end specialist-shop equipment — you will not find a carbon frame or a Shimano XT groupset — but for everyday use (getting to school, weekend rides in the Sierra de los Filabres or the Almanzora, getting around town) the level of components it fits is more than adequate for the price.

The practical difference from Toimsa, the brand we already knew well in the shop: Toimsa is designed for first bikes, with licences (Frozen, Batman, Peppa Pig) and stabilisers, in sizes from 12" to 20". UMIT picks up just where Toimsa ends and goes further: bikes from 18" to 29" with real gears, disc brakes on several models, and an adult range. If your son or daughter can already handle gears and wants something that looks like a "grown-up" bike, UMIT is the option we currently have in that range.

The UMIT range we have in stock, by age

Ages 3 to 6: first bikes with stabilisers (12"-14")

For this age the rule is simple: their feet should reach the ground with the saddle at its lowest position, and the bike should not be too heavy for their size. The UMIT Lydia 12" is the entry-level model: with a basket and a doll carrier, designed for girls aged 3-4 who are just starting out. It is in stock at €119.99.

If you need to choose by height rather than age, we have a full guide to children's bike sizes by height, which works just as well for UMIT as for any other brand: what matters is the inside-leg measurement, not the number printed on the box.

Ages 6 to 9: the step up to gears and bigger wheels (18"-20")

This is where UMIT starts to stand out from what we had before. The UMIT Casper 18" is unisex, with conventional V-brakes, ideal for children of 6-7 who no longer need stabilisers but are not yet ready for gears. It is in stock at €169.99.

For something with more character, the UMIT 20" BMX in neon blue has a rotor on the handlebars (so the handlebars can turn 360° without tangling the brake cables) and four pegs for simple tricks. It is the kind of bike requested by children who watch freestyle videos, and at €219.99 it is a reasonable way to try BMX without spending on a specialist-shop model.

Ages 9 to 13: junior mountain bike with wide wheels (20" fat)

The UMIT Spartan X 20" with 3.0 wheels is one of the new arrivals in this batch that we have liked most: a 7-speed Shimano gear system, front suspension and wide fat-bike-style tyres, which give much more stability on dirt tracks or country lanes. At €289.99 it is not the cheapest in the catalogue, but for anyone who lives where the tarmac ends quickly — which in the Almanzora is almost everyone — the difference compared with a narrow road tyre is noticeable.

Adults: 27.5" and 29" mountain bikes with disc brakes

For adults we have brought in two wheel sizes, which is the first real decision to make: the 27.5" accelerates and turns better in tight corners, while the 29" rolls more easily over stones and roots and holds its momentum better on flat ground or gentle climbs. For someone under 1.70 m, the 27.5" is usually easier to handle; above that, the 29" is welcome.

The UMIT Camaro 27.5" in black and red has a 6061 aluminium frame and hydraulic disc brakes, which brake with less effort at the lever and suffer less from heat than a mechanical disc. It is in stock at €379.99.

The UMIT Leopard 29" in green has 21 speeds and mechanical disc brakes, a step below hydraulic in braking feel but also easier to adjust at home if one day you need to tighten the cable. At €329.99, it is the entry-level option for anyone moving up to a big wheel.

Mechanical disc, hydraulic disc or V-brake: what changes

This is the question we are asked most when someone is choosing between two UMIT models that differ only in the brake:

• V-brake (calliper pads on the rim): what children's bikes like the Casper have. It brakes well for a child's weight and speed, is cheap to maintain and anyone can adjust it with an Allen key.
• Mechanical disc: the cable pulls a calliper that squeezes a disc on the hub. It brakes better than a V-brake in rain or mud because it does not depend on the state of the rim, and it is what the Leopard 29" has.
• Hydraulic disc: instead of a cable, a fluid transmits the force. Less force is needed at the lever for the same braking, and it does not lose feel with use, although if a bleed is ever needed that is a job for a workshop. It is what the Camaro 27.5" has.

For an adult bike that will be used seriously on tracks or in the hills, the hydraulic disc makes a noticeable difference. For getting to work on tarmac or a cycle lane, the mechanical one does the job perfectly well and is cheaper to maintain in the long run.

Steel or aluminium frame

The smallest children's bikes (Lydia 12", Romina 16") usually have a steel frame, which is heavier but also cheaper and stands up well to the typical knocks of a bike being parked by throwing it against the wall. The junior and adult models (Spartan X, Camaro, Leopard) have 6061 aluminium, which is lighter, something you notice above all when a child has to climb hills alone or when the bike has to be loaded into the car.

Price, stock and finance

Prices in this batch range from €119.99 (Lydia 12") to €379.99 (Camaro 27.5" hydraulic disc). Immediate stock is limited — we are talking about one or two units per model and size, because this is stock that has only just arrived — so if you are looking for a particular colour or size for a gift, it is better to confirm availability before coming to the shop. The rest of the UMIT catalogue that is not in physical stock we can get to order in 3-7 working days, with collection and assembly at our shop in Albox.

For the adult models, which are the most expensive, you can pay in instalments with Klarna; you can see the conditions on our finance page.

Basic maintenance that makes a UMIT bike last longer

A simple check every few months avoids most breakdowns: tyre pressure (shown on the side of the tyre), a greased chain without so much grease that it collects dust, and checking that the brakes do not rub when the wheel spins freely. On bikes with disc brakes, watch that the pads are not completely worn before they start to squeal: they are quick to change and cheap, whereas letting the disc get scored costs more.

Why buy from Híper Ocio

We are not going to say we are the cheapest bike shop in Almería, because we are not: there are cycling specialists with bigger catalogues and prices cut to the limit. What we offer is something else: four generations selling in Albox since 1923, the bike assembled in the shop before you take it away (it does not arrive in a box to assemble at home), and if anything goes wrong in the first few days we sort it out in person, not through a support ticket. For anyone living in the Valle del Almanzora, the Levante Almeriense or Los Vélez who does not want to depend on delivery or assemble the bike themselves, that is worth something.

Frequently asked questions

Do UMIT bikes come assembled?
The ones you buy in our physical shop in Albox are handed over assembled and checked. If you order one to order, it is assembled in the shop before delivery or dispatch.

Do you deliver UMIT bikes throughout Spain?
Yes. Unlike household appliances and televisions (which we only deliver with our own van in the Almanzora, Levante Almeriense and Los Vélez), bikes can be sent anywhere on the Peninsula.

What size UMIT bike does my 8-year-old need?
It depends more on height than on exact age. As a guide, between 120 and 135 cm usually corresponds to a 20" wheel, but we recommend consulting our size guide by height before deciding.

What is the difference between the UMIT Camaro 27.5" and the Leopard 29"?
Mainly the wheel size and the type of brake: the Camaro has a 27.5" wheel and hydraulic disc, easier to handle in corners and with smoother braking. The Leopard has a 29" wheel and mechanical disc, rolls better over stones and roots and is somewhat cheaper.

Can I pay for the bike in instalments?
Yes: when you complete your order you can choose Klarna, which shows you the instalment options available for your purchase before you confirm. You can see the minimum amount and the conditions on our finance page.

Can I return the bike if it does not fit my child?
You have 30 days from delivery under our returns policy. We recommend checking the size against the height guide before buying, to save yourself the hassle.
