10 Best Budget Electric Bikes 2025 in the UK

The VARUN Electric Bike is a solid choice for adults seeking a budget-friendly electric mountain bike with reliable features. It has a 250W motor that provides enough power to reach speeds up to 25 km/h (15.5 mph), which is standard for most electric bikes aimed at casual riding or light trail use. The 48V 13Ah (624Wh) battery offers a commendable range, allowing you to travel up to 100 km on a single charge, which is impressive for this price and practical for longer rides or daily commutes. The frame is made from lightweight yet durable aluminum alloy, making the bike easier to handle and sturdy enough for various terrains.

With 27.5-inch wheels and a front suspension fork, it strikes a good balance between comfort and control on bumpy roads or light off-road trails. The 21-speed gearbox provides flexibility to adjust pedaling effort depending on the terrain, which helps with climbing hills and riding efficiently. Safety is well covered by front and rear disc brakes, offering dependable stopping power in different weather conditions. The inclusion of a smart LCD display and an app for monitoring ride data adds a modern touch and convenience not always found in budget models. The bike also features a headlight and reflective elements, certified for road use, boosting visibility and safety.

The motor power is on the lower side compared to higher-end models, which might feel limited on very steep hills or for heavier riders. Front suspension only means rear bumps will be felt more, which is typical for bikes in this range but worth noting if you plan to ride rough terrains frequently. Assembly is mostly done but may require some effort, though clear guides are provided. This VARUN bike delivers great value with a good mix of power, range, and features suitable for beginners or riders looking for an affordable, versatile electric mountain bike for casual trails and commuting.

The Finbike U2 is a solid choice for anyone looking for a budget-friendly electric bike designed for city riding and daily commutes. It comes with a 468-watt rear hub motor that supports speeds up to 20 mph (about 32 km/h) and offers 5 different speed settings, which makes it easy to adjust your pace. The bike's 36V 13Ah removable battery is a highlight, allowing for convenient charging and providing a range of up to 75 km when using pedal assist mode, which is great for longer trips without worrying about running out of power.

With a sturdy iron step-through frame, the U2 is easy to mount and dismount, especially useful for riders of different heights or those wearing casual clothes. Its 26-inch tires are a common size that balances stability and maneuverability. The bike features dual suspension—front fork and seat post—which helps smooth out bumps on city streets, enhancing comfort on rougher surfaces. Safety is well covered with disc brakes combined with electronic braking, offering reliable stopping power in various conditions. Additional safety features include bright front and rear lights and reflective details on wheels and pedals, which boost visibility during night rides.

The 7-speed gearing system allows smooth shifting across different terrains, making it versatile for urban environments with hills. The bike supports up to 120 kg (about 265 lbs), suitable for most adults, and includes useful extras like a rear rack for carrying bags or groceries. The iron frame might make the bike a bit heavier (around 27 kg), which could be less convenient if you need to carry it upstairs or load it into a vehicle frequently. The maximum speed is limited to 20 mph, which is typical in this class but might feel slow for those used to faster electric bikes. Also, while the range is good, actual distance will depend on riding conditions and use of pedal assist. The Finbike U2 delivers a comfortable, practical, and safe ride for city commuters or casual riders who want a budget-friendly electric bike with decent range and features. It’s particularly suitable for riders seeking ease of use, stable handling, and reliable battery performance without breaking the bank.

The VARUN 24" Electric Bike is a solid choice for those looking for an affordable and practical electric bike mainly suited for city commuting and light off-road use. It comes with a 250W motor, which provides enough power for casual rides and gentle hills but may feel limited on steep or challenging terrains. The removable 36V battery offers a range between 30 to 50 kilometers, which covers most daily travel needs comfortably before needing a recharge. The frame is made from lightweight aluminum alloy, making the bike easier to handle and carry, while the front suspension fork helps absorb bumps, adding comfort on rougher paths.

This bike features single-speed gearing, which keeps things simple but may not be ideal if you want faster speeds or better hill climbing ability. Its 24-inch wheels strike a good balance between stability and maneuverability, suitable for teens and adults with adjustable seat and handlebar heights. Safety is well addressed with reliable dual disc brakes that work effectively in various conditions.

The bike includes three riding modes: pedal assist, normal riding without motor help, and a boost mode for extra power when needed, like on inclines. Assembly is mostly done before delivery, and the brand offers helpful instructions and support. However, the lack of multiple gears and a modest motor might not suit riders looking for more performance or longer, tougher rides. This makes the VARUN 24" Electric Bike a great option for beginners or anyone wanting an easy-to-use, lightweight electric bike for daily urban travel or short recreational trips. It combines good battery life, basic suspension, and strong brakes at a budget-friendly price, though it won't replace high-performance mountain e-bikes or multi-speed models.
