BOSTON FEMALE

Sturdy design

The frame is made of black lacquered aluminium. This makes the bike nice and lightweight, around 17.5 kg. So you can cycle on it just as well without any pedal assistance. The mudguards are made of metal and painted in the same colour as the frame. The bike is equipped with front and rear lights as well as reflective tyres so that you are always clearly visible in the dark. The handlebars and saddle are adjustable in height so that you can easily adjust it to your own, most comfortable sitting position.

You can easily add a front or rear carrier to the BOSTON. Both are specially designed for WATT by Steco from the Netherlands. The bike carrier has a load capacity of more than 25 kg, so you can easily and safely mount a children's bike seat on it. Just like all the other WATT bikes, the BOSTON has connection points for a safe ring lock and a sturdy bike stand. This makes it easy and safe to park your bike anywhere in the city.

Up to 25 km per hour assistance

The electric motor is located in the rear axle and has a power output of 250 WATT. The drive is activated via a rotation sensor (speed sensor) on the crankshaft. The motor has 5 levels of approx. 5 km to 25 km per hour of assistance. The levels are pre-configured, but you can adjust them to your own preferences yourself. You can find a manual for that here. A resistance of 2.86 is used in order to be able to cycle comfortably at higher speeds. This is the ratio between the front and rear gear teeth. Also referred to as the 'gear ratio'. Theoretically, this makes it harder to set off, but since the electric motor provides assistance practically immediately, you will hardly notice it.

Concealed battery

The bicycle draws its energy from a 36V - 10.5AH lithium battery. The bike is charged via a charger that you connect to your bike. A bit like charging your mobile phone. Charging a completely empty battery takes about three hours. The average lifespan of a battery is about three years or 500 charging cycles Keep in mind that the range of a battery can deteriorate after that. But replacing the battery is done in a flash. You can do this yourself or have it done at a bicycle repair shop. Follow the steps shown in the assembly video.

40 to 70 km range

How far you can cycle with a full battery (the range) is determined by a number of factors. It depends on your own weight, the assistance level you choose and the conditions that you are cycling in. For instance, with strong headwinds and assistance level 5, the range is shorter than on a flat road when the wind is behind you and you're using assistance level 1. Generally, you can expect to cover a distance of between 40 and 70 kilometres. More than enough for daily trips around town.
