Buying Guide
Realistic budget and expectations
New electric bikes under £300 are extremely rare and usually compromise on battery, motor or frame quality. Decide whether you mean new, second‑hand or a conversion kit, and expect shorter range and lower build quality at this price point.
Power, range and battery specs
Look for clear specs: motor wattage (250W is common for UK-legal eAPCs), battery capacity (Wh or Ah) and claimed range. Cheaper bikes often have small batteries limiting range to short commutes, so pick a model with at least a 7–10Ah battery or consider swapping batteries if possible.
Legal status and safety
In the UK an electrically assisted pedal cycle (eAPC) must have a motor no greater than 250W and assistance cut out at 15.5mph (25 km/h) to be classed as a bicycle. Ensure the bike meets eAPC rules, has proper brakes and a safe battery installation—cheap imports may not comply.
New vs second‑hand vs conversion kits
For under £300 you’ll often get better value buying a good second‑hand e-bike or fitting a reputable front/rear hub conversion kit to a solid bike. Second‑hand purchases allow you to inspect battery health and components, while kits let you keep a trusted frame and upgrade gradually.
Aftercare, warranty and spares
Budget models frequently come with limited or no warranty and poor spare‑parts support, so check returns policy and availability of replacement batteries, controllers and motors. Factor in potential extra costs for battery replacement, servicing or upgrades when comparing options.
Frequently Asked Questions
What is the best electric bike under £300 in 2026?
There’s no single best new e‑bike under £300 in 2026 — at that price you’re usually looking at used bikes, refurbished models or conversion kits. The best choice is a reputable second‑hand 250W eAPC with a healthy battery (tested cell voltage and range) or a well‑reviewed conversion kit fitted to a good frame.
Is an electric bike under £300 worth buying in the UK?
Sometimes — but only if you buy second‑hand from a trusted seller or purchase a quality conversion kit. New sub‑£300 models often skimp on battery and safety, so unless you’re prepared to check battery health and accept limited range, it’s usually better to raise your budget or buy used.
Which electric bike under £300 offers the best value for money?
Value usually comes from a well‑maintained second‑hand 250W eAPC or a reliable conversion kit fitted to a sturdy frame. Look for a bike with a 250W motor, a battery of around 36V and 10Ah (or equivalent Wh), and decent mechanical components—these attributes give the best combination of range and usability at low cost.
Ancheer vs Xiaomi vs generic budget brands — which should I buy?
Xiaomi (Himo) models typically offer better engineering and component quality than many unbranded budget imports, while Ancheer has been widely used in the budget segment but varies by model. At under £300 you’re more likely to find older Xiaomi or generic models used; prioritise known battery makers, good customer reviews and spare‑parts availability rather than brand alone.
Can I buy a legal e-bike in the UK for under £300?
It’s uncommon to find a new, UK‑legal 250W eAPC under £300; you’re more likely to find used legal e‑bikes or conversion kits that keep the bike within eAPC rules. If buying new at that price, verify motor power, top assisted speed and whether the seller states UK eAPC compliance.
Where should I shop for an electric bike under £300 in the UK?
Check reputable second‑hand marketplaces such as eBay UK, Gumtree, Facebook Marketplace, and specialist refurbished e‑bike sellers; also compare conversion kits from UK retailers and read reviews. Avoid sellers with no returns policy and ask for battery voltage and proof of recent use or service.
How long will the battery last on a cheap electric bike?
Battery lifespan depends on chemistry and usage; inexpensive lithium packs on budget bikes may start losing noticeable capacity after 18–36 months or a few hundred charge cycles. When buying cheap or used, ask for cycle count or test the range under a known load to estimate remaining life.
Are electric bike conversion kits a good alternative to buying a cheap e‑bike?
Yes — a reputable hub or mid‑drive conversion kit fitted to a solid bicycle often offers better value and reliability than a low‑end complete e‑bike. Kits let you choose a trusted frame, battery size and components, and can be upgraded over time; ensure the kit meets UK eAPC limits if you want legal pedal‑assist only operation.
