Electric Bike Conversion Kit 250W–3000W — The Guide That Helps You Choose Right

All4eBikes is your trusted destination for turning any bicycle into a high-performance electric bike. We offer a wide range of eBike conversion kits, Li-ion batteries, and compatible accessories, designed for riders in Romania who want more power, range, and comfort on every ride.

eBike Conversion Kits for Every Need

Whether you want an electric bike for daily commuting, off-road adventures, or relaxed rides, our range of conversion kits includes hub motors from 250W up to 3000W, compatible with most standard bicycles.

Motors for Urban Use

250W and 500W kits are ideal for daily commuting, being easy to install and visually discreet. They provide smooth pedal assistance, extending your bike's range without significantly changing its appearance.

Motors for Performance and Off-Road

For mountain trails, heavier loads, or strong acceleration, we recommend 1000W, 1500W, 2000W, or 3000W kits. These provide high torque, greater speed, and a riding experience close to that of a premium eBike.

Quality eBike Batteries, Compatible with Our Kits

A complete eBike conversion needs a reliable battery capable of supporting the power of your chosen motor. Our Li-ion batteries are available in 36V, 48V, 52V, and 72V versions, in downtube, triangle, or rear rack formats.

How Do I Choose the Right Voltage?

Battery voltage must match your controller and motor specifications. For 250W–500W kits, a 36V or 48V battery is sufficient. For 1000W or more powerful kits, we recommend 48V, 52V, or 72V for optimal performance and increased range.

Capacity and Range

Battery capacity, measured in Ah, determines how far you can ride on a single charge. For daily commuting, 10–15Ah may be enough, while for long rides or intensive use we recommend batteries of 17.5Ah, 20Ah, or more.

All All4eBikes batteries are equipped with a BMS protection system for safe charging and discharging.

Accessories and Parts for Your eBike Conversion

Besides motors and batteries, we offer a full range of eBike accessories: LCD displays, thumb and twist throttles, PAS sensors, controllers, brake levers with sensors, and torque arms for added safety.

Easy Installation at Home

Most of our kits are designed for self-installation, with the help of guides available on our blog. For more complex setups, we recommend installation at a specialized service center.

All orders benefit from free shipping in Romania for orders over 500 RON, a 12-month warranty, and dedicated technical support to help you at every step of your eBike conversion.
