Due to a black painted aluminum frame, we are able to provide a strong bike that only weights around 17.5 kg. This allows you to easily cycle without with or without pedal assistance. Furthermore, the bike is equipped with front and rear light and reflective tires, so that you are always visible in the dark. The handlebars and saddle are height adjustable to provide you with your most comfortable sitting position.
You can easily expand the BOSTON with a front or rear rack. Both these racks where specially designed for WATT by Steco. The rear rack has a load capacity of more than 25 kg, making it easy and safe to mount a child seat on it. Additionally the BOSTON has connection points for a secure ring lock and a kickstand. Allowing you to easily and safely park the bicycle anywhere in the city.
Up to 25 km per hour support
The BOSTON has a 250-WATT electric motor in its rear axle, and a rotation sensor in the bottom bracket to regulate the drive. The motor has 5 levels of assistance from 5 km to 25 km per hour support. The modes are pre-set, but you can adjust it according to your wishes. To be able to cycle at a higher speed, we used a gear ratio of 2.75. This is the ratio between the front and rear sprockets. Acceleration is therefore theoretically heavier, but because of direct support by the electric motor, you will barely notice it.
The bike gets its energy from a 36V - 10.5AH lithium battery developed by Samsung. To charge your bike you will get a charger that connects to the bike itself, comparable to charging your mobile phone. Charging a completely empty battery takes about 3 hours. The average battery life is about three years or about 500 charge cycles. Keep in mind that the range of a battery can decrease after that. Replacing the battery is easily done via the head tube. You can do this yourself or have it done by a bicycle repair shop. Follow the steps from the installation video.
40 - 70 km range
How far you can cycle with a full battery (the range) depends on a number of factors. It depends on your own weight, the support mode you choose and the cycling conditions. For example, with strong headwind and support level 5, the range is smaller than on a flat road and support level 1. In general, you can assume that you can cover a distance between 40 and 70 kilometres. More than enough for your daily trips around the city.
