Choosing an electric bike: a practical guide to commuting and leisure

An electric bike can make everyday journeys easier, but an attractive price or impressive range doesn’t tell you everything. With e-bikes in particular, unclear battery specifications, unsuitable tyres or a frame that’s awkward to transport can lead to a purchase you regret.

So don’t focus only on the wattage or a promised range. Check the dimensions, weight, brakes and charging time, as well as the rules for using the bike on public roads in the Netherlands.

Common pitfalls when choosing an electric bike

1. Focusing only on motor power

A 250W electric bike often falls within the usual specifications for a standard e-bike. However, the level of assistance, speed limit, weight of the bike and hills along your route also affect how comfortable it is to ride.

A higher peak power doesn’t automatically mean that a bike delivers more power continuously. Check whether the stated 250W is the rated power, and whether any additional claims are clearly presented as product information from the brand.

2. Treating the range as a fixed distance

An electric bike with a long range won’t cover the same distance in every real-world situation. Rider weight, tyre pressure, wind, temperature, hills and your chosen assistance level all affect energy consumption.

For example, a 48V 18.2Ah battery contains more energy than a smaller battery pack, but the stated range is still only a guide. According to the Mangosteen FT03 product description, its maximum stated range is 75 km. Don’t treat this as a guaranteed distance for every route.

3. Overlooking comfort and transport

A heavy fat bike can feel stable, but it’s harder to lift or take with you. A folding electric bike is more convenient for a flat, train journey or small storage space, but always check its folded dimensions and total weight.

Small wheels also make a difference. A 14-inch tyre, like the one on a mini e-bike, handles uneven paving differently from wide 20-inch tyres. Choose a bike to suit your regular route, not just its appearance.

Which specifications deserve extra attention?

Battery capacity and charging

Pay attention to the combination of voltage and amp-hours. A 36V battery with 10Ah has a different energy capacity from a 48V battery with 18.2Ah. A removable battery is handy if you want to charge it at work or live somewhere without a dedicated bike storage area.

Also check:

  • Whether the battery is removable;
  • Whether a charger is included;
  • How long a full charge takes;
  • Whether replacement batteries will be available later;
  • What warranty and returns terms apply.

Safe use is important with lithium-ion batteries. Stop charging if you notice an unusual smell, deformation or excessive heat, and always follow the manufacturer’s instructions.

Brakes, tyres and suspension

For city journeys, standard tyres and mechanical or hydraulic disc brakes may be enough, depending on the model. Wider tyres provide more contact with the ground on unpaved paths, but they usually add weight and rolling resistance too.

According to the product description, the Mangosteen FT03 has 20 x 4.5-inch fat tyres, dual suspension and hydraulic disc brakes. The bike weighs 42 kg and has a stated maximum load of 120 kg. This makes it less suitable if you regularly need to carry it up stairs.

Dutch road rules

A standard e-bike usually provides assistance up to a maximum of 25 km/h and is pedal-assisted. Before buying, check that the model meets Dutch requirements. A throttle, higher design speed or different controls may affect its legal classification.

Also check the lights, reflectors, bell, brakes and manual. A seller’s product information is no substitute for checking the current Dutch rules.

Frequently asked questions about electric bikes

How far can an electric bike travel on a single charge?

It depends on the battery capacity, assistance level, speed, temperature, tyre pressure, route and total weight. Treat the stated range as a guide. If you commute every day, it’s wise to leave some extra room, so a headwind or detour doesn’t leave you with a flat battery.

How long does an e-bike battery last?

Battery life depends on charging cycles, storage temperature, use and maintenance. Store a lithium-ion battery in a dry place and follow the manufacturer’s instructions. Don’t leave it completely discharged for long periods, and before replacing it, check that the voltage, connection, capacity and bike platform are compatible.

Is a 250W electric bike legal in the Netherlands?

A model with pedal assistance up to 25 km/h generally falls under the rules for a standard electric bike, but the complete specification determines its classification. Check the controls, speed, lights, brakes and documentation. If in doubt, consult the latest information from the Dutch government or RDW.
