Battery capacity
Our system is open, so it works with third-party batteries. However, we suggest using our batteries because they are designed to deliver at least 25Amps continuously and 35Amps intermittently. You can select your battery here. Consider the following:

• 220Wh 36V: this battery only fits the 250W motor and is recommended if you are well-trained and do not need much or prolonged support from the motor. As a guideline, this type of battery can reduce your effort by 50% for a two-hour ride.
• 600Wh 48V: this battery is compatible with all motor power levels. It is recommended if you need prolonged support from the motor. Additionally, this battery is equipped with a battery management system (BMS) that protects the battery from overcharging, short circuits, overheating, and excessive discharge. The battery has a capacity of 600 Wh and a voltage of 48 V.
• 800Wh 48V: this battery is compatible with all motor power levels. It is recommended if you need prolonged support from the motor. Additionally, this battery is equipped with a battery management system (BMS) that protects the battery from overcharging, short circuits, overheating, and excessive discharge. The battery has a capacity of 800 Wh and a voltage of 48 V. It is recommended for long trips with climbs of about 2000-2500 meters in altitude.

Below are the dimensions:

• Bottle holder battery 220Wh: 25 x 8 x 9 cm

• Bottle holder battery 600Wh: 36.5 x 9 x 9.5 cm

• Bottle holder battery 670Wh: 36.5 x 9 x 9.5 cm

• Bottle holder battery 800Wh: 37 x 11 x 9.5 cm

The "Backpack" configuration includes:

• 600Wh bottle holder battery

• Backpack battery support

• Extended cable with magnetic safety connector for easy release.

Custom batteries

If the available battery models are not compatible with the lines of the bicycle frame chosen for the conversion, Bikee Bike offers the possibility of designing and producing custom batteries. More information HERE.

All batteries come with a lock, keys, battery support, high-current BMS, and high-current cable with connector. Additionally, all batteries are supplied with a 3A charger.

Want more options? Check out our configurator on the dedicated Lightest site, here.

In the advanced configurator you can also choose the following products:
Chain protection (selectable exclusively in the advanced configurator):
It is highly recommended if you are not riding a racing bike. Like in a normal bike, the chain protection prevents the chain from falling off.

Legal vs Offroad (selectable exclusively in the advanced configurator):
In the Legal version, the motor stops assisting at the legally limited speed, as follows: 250W: the legal speed is 25 km/h 500W: the legal speed is 25 km/h 750W: the legal speed is 32 km/h (or 20 mph) 1000W: the legal speed is 32 km/h (or 20 mph) The Offroad version has no restrictions, so the motor assistance will not stop at the indicated speed but will continue to assist you. Since this is not allowed in many countries, we advise you to check your country's laws and use your motor accordingly. If you buy the Offroad version and the Superhero Pack, you can activate and deactivate the speed limitation via the smartphone app, simply by pressing the "RACE" button. In this way, your Offroad motor can function as a "legal" motor when you want, but note that using a motor that can be unrestricted may not be legally allowed on normal roads in your country.

Version (selectable exclusively in the advanced configurator):
The torque of your Standard version depends on the motor power version: 250W: the maximum torque is 70 Nm 500W: the maximum torque is 90 Nm 750W: the maximum torque is 90 Nm 1000W: the maximum torque is 90 Nm You can unlock the full potential of your Lightest ebike kit by purchasing the High Torque version, to bring the torque to maximum levels: 250W High Torque: 90 Nm 500W High Torque: 120 Nm 750W High Torque: 120 Nm 1000W High Torque: 120 Nm   What differentiates torque from power? Torque will push you uphill and give you acceleration on flat roads, while power will give you speed both uphill and on flat roads. The High Torque option is completely legal.

Motor support (selectable exclusively in the advanced configurator):

• Short Mount: fits classic triangle-shaped frames, with the motor positioned under the down tube. It is perfect when the down tube is perfectly straight and can work with sprockets up to 36T. You can download the drawing here: Lightest Short Mount to check if it matches your frame.

• Medium Mount: fits classic triangle-shaped frames, with the motor positioned under the down tube. The main difference compared to the Standard support is the length: the Medium support is about 40 mm longer. This keeps the chain higher on the sprocket. It is perfect when the down tube is not perfectly straight or when you need a sprocket larger than 36T. Additionally, this support has an option for an extra spacer to give more stability and rigidity to the installation. This is a must for Fat Bikes. You can download the drawing here: Lightest Medium Mount to check if it matches your frame.
• Inframe Mount: fits frames with a bent down tube, the motor is located inside the frame if there is space. You can download the drawing here: Lightest Inframe Mount to check if it matches your frame.
• Hybrid Mount: it is the Medium Mount plus the Long Mount motor support. You can download the drawing here: Lightest Hybrid Mount.
• Long Mount: fits frames with a bent down tube, the motor is located under the down tube. You can download the drawing here: Lightest Long Mount to check if it matches your frame.
