5 Cosas You Should Saber Antes de Comprar Bicicletas Eléctricas

Before switching models, try this

Muchos cambian de producto cuando el problema estaba en un detalle de uso or de mantenimiento. Antes de gastar, repasa esta lista: es más barata que una compra nueva y en bastantes casos resuelve el problema from the todo.

The mid-drive motor and the hub motor completely change the bike

A mid-drive motor (at the bottom bracket) pushes through the drivetrain, so use the gears: it climbs hills with real force, keeps the weight centered and low, and the bike handles naturally. A motor in the wheel hub is cheaper and quieter but always pushes the same regardless of the gear, which shows badly on long climbs, and it throws off the weight distribution. If you're going to ride terrain with gradients, the difference is huge and justifies the extra cost.

Batería integrada or extraíble no es una cuestión estética

A battery removable you carry it up to charge, swap it for another on a ride and can replace it without a workshop when it ages. A integrated in the frame queda más limpia y protegida, pero obliga a llevar la bici al enchufe y, en algunos modelos, a pasar por taller para sustituirla. Si aparcas en la calle or en un garaje sin corriente, la extraíble no es una preferencia: es la única opción viable.

The torque sensor is what makes an e-bike feel good

This is the difference between a bike that responds and one that surges. A cadence sensor only detects whether the pedals are turning, so the motor kicks in suddenly and with a delay: the bike surges on its own and then cuts out. A torque sensor measures how much force you apply and multiplies that force proportionally, so the assistance feels like having stronger legs. It's the component that most defines the experience and the one most cut back on cheap models.

An e-bike's motor wears out the drivetrain much faster

The extra power runs through the same chain, the same sprockets and the same chainring as on a conventional bike, and wear speeds up noticeably. A chain that lasts thousands of kilometers on a normal bike may need replacing much sooner on an e-bike. What saves money is measuring chain stretch with a gauge and replacing it in time: a cheap chain replaced in time saves an expensive cassette and chainring.

Watt-hours, not amp-hours, tell you how far you'll get

A battery advertised as "15 Ah" isn't comparable to another at "13 Ah" if they have different voltages. The useful figure is Wh = volts × amp-hours: una de 36 V y 15 Ah son 540 Wh, y una de 48 V y 13 Ah son 624 Wh, más capacidad aunque el número de Ah sea menor. Como referencia práctica, un ciclista consume from the orden de 7 to 15 Wh per kilometer depending on the assistance level, the terrain and the total weight.

Parking and traffic rules change from city to city

For traffic purposes an EPAC is a bicycle, so it generally rides in the bike lane and on the road according to local bylaws, but each town regulates sidewalks, parks and parking differently. There are cities where a helmet is compulsory for minors, others with specific speed limits in pedestrian areas. Before using it daily to commute, half an hour reading the local bylaws avoids avoidable fines.

To wrap up

Apply what's above first, since that's what makes the biggest difference, and leave the rest for once you've got some experience. If after that you're still not getting what you're after, then it does make sense to switch gear: the Fafrees F20 Ultra is the most well-rounded option to make the jump, with the Fafrees F20 Pro as an alternative.

Frequently asked questions

Motor central or en la rueda?

Mid-drive if there are hills: it uses the gears, climbs with real force and the bike handles in balance. In the wheel if it's all flat city riding and you're after price: it's cheaper and quieter, but it always pushes the same and bogs down on long climbs.

Cómo la protejo from the robo?

A a high-end U-lock anchored through the frame a un punto fijo, más un segundo candado para la rueda, y llevarte la batería si es extraíble. Revisa tu seguro de hogar: muchos cubren la bici solo dentro from the domicilio, así que un seguro específico puede tener sentido dado el valor from the vehículo.

Sirve para hacer ejercicio?

Yes, and in practice more than it seems: it changes your range, it doesn't remove the effort. On low assistance you pedal just the same, and with the help you take on trips and routes you didn't do before. Mobility data is consistent: people with an e-bike clock up more kilometers per month than people with only a conventional bike.

Cuánto durará la batería antes de perder capacidad?

It's measured in charge cycles, not years, and the degradation is gradual: you'll first notice fewer kilometers, not a sudden failure. With good care, several hundred cycles while keeping most of the capacity. Check before buying whether the battery is sold separately para ese modelo: eso decide si la bici dura una década or se convierte en chatarra.

Puedo desbloquear el limitador de 25 km/h?

Technically yes, legally it's a serious change. Once it exceeds the limits it stops being a bicycle and becomes a vehicle that requires type approval, registration and insurance; on top of that the manufacturer voids the warranty and, in an accident, the insurer may refuse to cover it. It's not a minor modification.

Should I go with the Fafrees F20 Ultra or the Fafrees F20 Pro?

The Fafrees F20 Ultra is the most well-rounded option and the one we recommend by default. The Fafrees F20 Pro makes sense if your priority is Everyday Use. As a budget reference, the sensible range starts around €150 and the best balance is usually around €240.
