Convert leisure bicycle into electric:

This kit is specifically designed to transform a leisure bicycle into an electric bike with nothing to envy from similar format e-bikes. In fact, the components it incorporates, starting with its battery of up to 16Ah, are of top quality and designed to operate optimally for years. For better integration into city bikes, there is the option to acquire the battery with a rack compatible with any frame.

Electric bike kit components for city bikes:  

1x Brushless motor from the kit: Hub motor with a nominal power of 250W and limited to 25 km/h in compliance with current EU regulations. The motor can be placed in the front or rear wheel and is fixed to a rim compatible with your bike. Kits for handbikes and tricycles only offer the option of a front hub motor.

1x Lithium-ion Battery Electric Kit: 36V Lithium-ion Battery. Each battery is manufactured on demand to guarantee optimal performance. You can choose from various formats and battery capacities (Wh) according to your cycle's morphology and autonomy needs.

The electric bike kit for leisure bikes is available with two types of batteries:

Battery or Battery with Rack:: 


1X 15A FOC (Field Oriented Control) Controller: High-end controller that offers several advantages over the square wave/modified wave controllers marketed with other kits or electric bikes, including: 1) Less noise and heating, 2) Better control of the assistance level, making it more progressive and protecting the motor. 3) Greater efficiency on hills at low assistance levels. In kits with grid or drawer type batteries, the controller is located in the battery base itself, which is fixed to the frame. In kits with bottle or triangle type batteries, the controller is located in a PVC box with clamps that is attached to the frame of your bike.

Electric Bike Kit Warranty

Maximum speed. In compliance with the applicable European regulations for electric bicycles with pedal assist, our kits are limited to a maximum speed of 25 km/h. Failures resulting from the modification of the maximum speed parameter by the user will not be covered by the kit warranty, so in order to ensure safe use, it is not recommended to manipulate the factory settings of the kit.

Type of use. This kit is not suitable for extensive use in areas with steep slopes such as mountain passes and slopes over 300 meters. Failures resulting from this type of use will not be covered by the product warranty. On moderate urban slopes and inclines, it is recommended not to exceed level 2 of assistance and to complement the use of the motor kit with appropriate pedaling effort to avoid overstraining the motor at all times.

Battery autonomy. Fotona Mobility guarantees that the technical data of the battery (Voltage, Ah, Wh) shown in this product sheet are real and offers a 3-year warranty against manufacturing defects in Spain. The autonomy data (km) listed in each battery option are estimates based on moderate use and our own experience, as they depend on at least three factors: 1) User weight 2) Terrain slope, and especially 3) the selected level of assistance. For greater autonomy and battery life, it is recommended to use a moderate level of assistance and recharge the battery after each use.
