Remember that even the best laced wheel requires check the spokes after driving a certain distance. Usually, the first tightening of the spokes is carried out after the first 50-200 km depending on the driving style. If the spokes are starting to rattle, it is a sign that they are on the wheel and should be finally correct.
CONTROLLER
Sinewave controller compared to classic squarewave controllers allows for a smoother ride, reduces energy consumption and makes the motor quieter.
The controller comes with a collective cables with HIGO connectors (Connection of a throttle, display, brake sensor).
Display with button panel for KT series programmable controllers.
What is the difference between the KT-LCD3, KT-LCD4, and KT-LCD8s displays? See a detailed description of the functions and parameters - Click here.

48V | 17,5Ah | 840Wh | EVE INR18650-35V
48V | 20Ah | 960Wh | Samsung SDI INR21700-50E
Range Eco
Approximate range in summer at 25-27 km/h and 20% motor assistance
17,5Ah - 102 km20Ah - 120 km
Range Standard
Approximate range in summer at 25-27 km/h and 50% motor assistance
17,5Ah - 82 km20Ah - 96 km
We provide the highest quality
Documentation - The battery has the necessary documents: CE, MSDS, UN38.3 and meets the standards EMC 2014/30/EU, IEC 62133-2-2017
Performance - NEW Li-ion cells EVE and Samsung ensure the longest possible battery life and maximum range.
Safety - The battery is maintenance-free because all control over its operation is exercised by the BMS (Battery Management System). The built-in BMS with a power of 30A protects the battery against excessive discharge and overcharge, optimizes battery operation and balances the voltage between individual cells.
Simple assembly - The battery case includes a rail with holes intended for installation in a bicycle frame. Additionally, the set includes rivet nuts and screws enabling strong installation of the battery. Additional stabilization on the frame is provided by 4 plastic pads.
Convenient use - Slide the battery into the rail and lock it before sliding out by turning the key. With one move, we can also dismantle the battery and move it to another place for e.g. charging or transport.
Full control - The battery has a built-in battery charge indicator that allows you to quickly determine the remaining range of the bike.

Why our kits?
Feedback
It all began with the Nexun. We have tens of thousands of customers, users of our sets. We supply hundreds of workshops with electric bicycles in the country and abroad. We sell products that have been trusted by a large number of users. Wherever you will find any mention of us - these are positive opinions.
Experience
10 years of experience in the industry make us experts with proficiency in the field of electric vehicles. We will provide professional advice before buying, advise or dispel technical doubts. We will help with any problem and we will not leave anyone in need.
Reliability
We know that failure-free operation is crucial, which is why we do not assemble our kits based on small, overloaded components. We do not artificially raise the power of motors, adjusting their parameters to the limits of their durability. We do not have you with numbers, watts and other wonders, so we do not offer small-size controllers that are usually overclocked in other sets "on the Internet". We always select the elements of the set so that they have the appropriate reserve. We always design and build packages and batteries based on knowledge and experience. We do not overload the power supply - our batteries are built for many years of operation in mind.
The best sets
Our kits are the cheapest and the richest in important and essential parts. We do not add unnecessary things to our sets, we do not inflate the price and we do not sell unnecessary elements by force. We do not have hidden costs.
Spare parts
Check our offer. We are the only company to provide such a wide range of spare parts for our products. With us, your set will work much longer, because you have constant access to spare parts as well as advice and assistance in repairs. We conduct teaching through channels on YT, and Blog. You can also find us on FB and forums with electric vehicles.

The store guarantees repair or replacement of equipment for up to 24 months for consumers and up to 12 months for companies from the date of purchase. Complete the complaint form available on the store's website.
What is not covered by the warranty?
- Errors in installation or incorrect mechanical maintenance - Thermal damage (overheating of the motor, controller, phase connectors) - Independent modification or repair of set elements - Consumables (wear items): Hall sensors, power cable, axle, bearings, gear module and clutch. - Mechanical damage caused by incorrect use of the product. E.g. damage from falls, excessive mechanical loads
Each battery in the nexun.pl online store is covered by a 24-month warranty.
The warranty covers: - Cell damage - BMS damage - Capacity decline (over 15% per year)
The warranty does not cover: - Errors in assembly that do not comply with the instructions or workmanship - Improper maintenance - Mechanical damage (cracked/broken casing, melted connection terminals, etc.) - Changes in the product's operating characteristics depending on weather conditions (temperature) - Water damage
To maximize battery life, use the following recommendations: 1. Fully charge the battery after each ride 2. Fully charge the battery every 3-4 weeks when you do not use it, e.g. winter break. 3. In the autumn and winter (temperature below +12*C), lithium-ion batteries have a lower capacity (by max. 30%) than in the summer, which results in a shorter range. This is normal. During this period, do not use the full power for the first 10-15 minutes of riding. 4. Do not charge the battery with a current higher than 3A.
