When you compare bicycles for repairability, check four things: whether a shop can swap the battery, whether the firmware accepts a compatible replacement, how long spare parts stay on sale and what they cost, and whether a basic toolkit can service the bearings. Batteries and firmware are now set by EU law, while bearing design is judged on industry practice. A repairability score is a rating of how easily a product can be taken apart, fixed and kept running with parts you can still buy.
These factors carry different weight. From February 2027, the EU sets hard rules for e-bike batteries, so a manufacturer either meets them or does not. Bearings, frames and most mechanical parts sit outside any official scoring system. That means manufacturers, shops and riders each need to know which claims a regulator backs and which rest on design judgement.

What EU law requires for e-bike batteries
EU Regulation 2023/1542 on EUR-Lex requires e-bike batteries to be easy for independent professionals to remove and replace for the product's whole life, starting 18 February 2027. The regulation groups e-bikes under "light means of transport", or LMT. The duty covers repair by professionals, not owners, so a battery can still need workshop tools and meet the rule. Under Article 11, manufacturers must sell LMT batteries as spare parts for at least five years after the last unit of a model goes on sale. The price has to be reasonable and non-discriminatory for independent repairers and end users alike.
An independent shop should therefore pay the same kind of price as a brand dealer. LMT batteries sold in the EU from the same date also need a digital battery passport. TÜV Rheinland describes it as a record of battery information that shops and owners can use when deciding between repair and replacement. The rules apply only to products placed on the EU market from 18 February 2027. An e-bike bought before then comes with none of these guarantees, as Intertek notes.
How to judge firmware lock-out
Firmware is the software built into the motor, battery and display. Some systems use it to reject any battery that is not the brand's own. The European Commission's guidance on Article 11 says Article 11(8) bans using software to block a swap to a compatible battery or its key parts.
Firmware may still check a replacement for function and safety. The line falls between a safety check and a brand lock. A system that rejects a compatible, working battery only because of who made it fails the test. Questions worth asking before you buy or stock a model:.
- Does the system accept compatible batteries, or only the brand's own part numbers?
- Can an independent shop run the diagnostics a battery swap needs?
- Does a firmware update ever change which batteries the bike accepts?
Why the bottom bracket is the best bearing check
No official bicycle repairability standard scores bearings. The bottom bracket, the bearing set the cranks turn on, still gives buyers a practical test. BikeRadar's bottom bracket guide explains that threaded standards such as BSA and T47 come out and go back in with simple hand tools. The frame shell can also be refaced.
Press-fit bearings need a bearing press and a frame machined to tight tolerances, or they may creak. For a rider, this shows whether a home mechanic can do the job or whether it has to go to a shop. For a shop, it decides which tools you need and how likely a customer is to return with a creak. A threaded shell is the lower-risk choice for a bike you plan to keep for many years.
What France's scoring model adds
France's repairability index gives a working template for scoring a bike. The European Environment Agency says it rates products from 0 to 10 on five criteria: Sources disagree on when the index covers electric-assist bikes. One guide says it began in July 2025, and another describes the rules as still in draft with 2026 expected. Check the label on the bike rather than assuming a score exists.
France also has two bike-specific labels that measure other things. Cyclescore rates bikes A to E on environmental and social impact. Indice France Vélo marks bikes designed, assembled and made in France with a large share of French parts. Neither one is a repair score.

A comparison checklist for each group
Manufacturers selling in the EU from February 2027 should confirm three things. Batteries must be removable by independent professionals, spare batteries must stay on sale for five years, and firmware must not reject compatible parts. Bearing design and published documentation are where a brand can stand out, since no law sets them. Shops should rank models by how much work an independent shop can do without dealer tools.
That includes battery swaps, diagnostics access, and whether the bottom bracket is threaded or press-fit. The ratio of part price to bike price, borrowed from the French index, is a quick way to compare brands. Cyclists should weigh the purchase date first. A pre-2027 e-bike carries no EU guarantee of a replaceable battery or spare-part supply. Even on a newer bike, the law promises professional repair, so the battery may still need a shop visit.
Frequently Asked Questions
Will the EU rules let me replace my e-bike battery myself?
Not necessarily. The regulation requires removal and replacement by independent professionals, not by owners.
Can a manufacturer still refuse to sell me a spare battery?
For LMT batteries covered by the rules, spare batteries must be sold to end users as well as repairers, at a reasonable, non-discriminatory price, for at least five years after the model's last unit goes on sale.
Is a Cyclescore rating the same as a repairability score?
No. Cyclescore rates environmental and social impact from A to E, not how easy a bike is to repair.
