A 21-speed mountain bike may initially seem like a versatile choice for commuting to school or work, leisure rides and off-road paths. However, the number of gears does not tell you everything. The wrong frame size, poor adjustment or unclear electric drive system can make your bike less comfortable or safe to ride than expected.
This buying guide explains what to look out for if you live in the Netherlands. Afterwards, you’ll find practical product choices for adults, young people and children.
21 gears sounds impressive, but the quality of the shifters, cables and derailleur also affects how smoothly you change gear. You do not always need all the gears on flat Dutch cycle paths. A wide gear range can be useful on bridges, flyovers or unpaved roads.
So don’t just look at the number. Also consider:
A 24-inch mountain bike is not automatically suitable for every young person, nor is a 26-inch mountain bike suitable for every adult. Your height, inside leg measurement and riding position are more important than age alone.
According to the product information, the 24-inch version of the BAMCBASE Sprague is intended for riders measuring approximately 4'3" to 5'2". The same information states that the 26-inch version is intended for riders measuring approximately 5' to 5'8". Use this as a guide, and check the current size chart and maximum user weight before buying.
Many bikes bought online arrive partially assembled. With the Sprague, you need to fit the handlebars, pedals, saddle and front wheel, among other parts. Before your first ride, check that:
With a BMX bike fitted with stunt pegs, you should also check the rotor and footrests. With an electric bike, you also need to check the battery, charger and electrical connections.
A Hi-Ten steel frame is a specific material specification. It may be suitable for everyday use, although the frame may be heavier than an aluminium one. A softer foam saddle can feel comfortable on shorter rides, but the correct saddle height remains more important than the padding alone.
The Sprague uses V-brakes. These are relatively easy to maintain and adjust. Check the brake pad wear regularly. When riding in the dark, lighting and visibility are just as important as brakes. Check that the version you choose has the equipment required for use on public roads.
The product description mentions grip and puncture resistance among the features of the XC tyres. These are properties stated in the product information; the actual service life depends on tyre pressure, surface, load and maintenance.
A bike should be adjusted so that you can mount, brake and dismount with confidence and control. Look for:
An adult MTB bike with 26-inch wheels may suit shorter adults and older young people, while a 24-inch model may be a better fit for shorter riders. A mountain bike for women and men does not automatically differ in its technical features; fit and adjustability are more important than the marketing category.
The DYU D3S product name describes it as an electric bike with a 250W motor, 36V10Ah battery, 14-inch tyres and a folding design. The product name also refers to it as a mini e-bike and folding electric bike. Before buying, check the current product specifications for the speed, range, pedal assistance and charging procedure.
A city bike with electric assistance must comply with the applicable rules for electric bikes in the Netherlands. Check the maximum assisted speed, how the assistance operates, and whether the bike has the required lights and reflectors. Do not base your choice solely on motor power.

We’ve put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
It can be, particularly if you’re looking for a bike for commuting to school or work, leisure rides and a variety of surfaces. For flat urban routes only, a simpler drivetrain may be sufficient. Above all, check the riding position, brakes, lighting and tyres.
Its lifespan depends on how it is used, stored and maintained. Keep the tyres inflated, lubricate the chain regularly, and check the brake pads, cables and bolts. Ideally, store the bike indoors in a dry place, and have any damage or poorly functioning brakes repaired before riding.
In addition to the purchase price, you’ll need to account for electricity, maintenance, tyres and possibly a replacement battery in the longer term. The actual distance per charge varies depending on weight, speed, temperature, tyre pressure and route. So check the stated battery capacity and usage conditions before placing your order.
