Yes. In England and Wales, taking someone else’s bike without the owner’s consent is a criminal offense, even if you planned to bring it back. It falls under section 12(5) of the Theft Act 1968, which covers taking a pedal cycle for your own or another person’s use without the owner’s consent or other lawful authority, and riding one you know was taken that way. It is lighter than theft: magistrates’ court only, no prison sentence, and a maximum fine at level 3 on the standard scale, which is £1,000. A genuine belief that the owner would have agreed, had they known, is a defense.
This page covers England and Wales as at 9 October 2026 and is general information, not legal advice. legislation.gov.uk marks section 12 as applying to England and Wales, so readers in Scotland or Northern Ireland should check the law where they live.
What section 12(5) actually says
Section 12 of the Theft Act 1968 is headed “Taking motor vehicle or other conveyance without authority”. Its general offense, in subsection (1), covers conveyances of all kinds. Subsection (5) says that general offense does not apply to pedal cycles, then creates a version for them alone. The Crown Prosecution Service (CPS) guidance on Theft Act offenses describes the same arrangement: pedal cycles have a specific offense of their own under section 12(5).
The cycle offense has two parts:
- Taking. You take a pedal cycle, for your own use or someone else’s, without having the owner’s consent or other lawful authority. The question is consent, not whether you meant to keep the bike.
- Riding. You ride a pedal cycle knowing it was taken without that authority. For the same “knowing” wording in the general offense, CPS guidance says belief falling short of knowledge is not enough, so a hunch that a bike was taken does not meet the test.
The general offense has a third part that the cycle wording does not repeat: allowing yourself to be carried in or on a conveyance you know was taken without authority. The cycle offense as written names only taking and riding.
How it differs from theft
Theft requires dishonestly appropriating property that belongs to someone else, with the intention of permanently depriving them of it (section 1 of the Act, as summarized by the CPS). Taking a bike for a ride without asking, fully intending to return it, lacks that last element, so the pedal-cycle offense is the more likely fit.
The line can move. CPS guidance says intent to deprive permanently can exist where someone intends to treat an item as their own to dispose of regardless of the owner’s rights. If the plan is to keep the bike, the conduct may be charged as theft instead, which a court decides on the facts.
| Offense | Where it is tried | Maximum penalty |
|---|---|---|
| Taking a pedal cycle without consent (section 12(5)) | Magistrates’ court only (summary only) | Fine up to level 3 (£1,000); no prison sentence |
| Taking any other conveyance without consent (section 12(1)) | Magistrates’ court only (summary only) | Six months’ imprisonment, an unlimited fine, or both |
| Theft (section 1) | Either way: magistrates’ court or Crown Court | In the Crown Court, seven years’ imprisonment and/or an unlimited fine |
“Summary only” means magistrates hear the case without a jury, and “non-imprisonable” means prison is not an available sentence; CPS guidance uses both terms for the pedal-cycle offense. Level 3 sits on the standard scale of fines for summary offenses; in the current column of the table in section 122 of the Sentencing Act 2020, it is £1,000.
The defense for people who honestly thought it was fine
Subsection (6) of section 12 says you do not commit an offense by anything done in the belief that you have lawful authority to do it, or that you would have the owner’s consent if the owner knew of what you were doing and the circumstances. CPS guidance confirms this defense applies to every offense under section 12, taking a pedal cycle included. Three points follow from the wording and that guidance:
- It is about belief. The statute asks what you believed when you acted.
- The prosecution carries the burden. Once the defense is raised as an issue, CPS guidance says the prosecution must disprove it to the criminal standard.
- A court judges the facts. Having ridden a housemate’s bike with their blessing before is a very different position from taking a stranger’s unlocked bike.
Consent also has edges. For the general offense, CPS guidance gives a car example: where an owner has given permission for some limited purpose, keeping the car after that purpose is finished and continuing to drive it is an offense if there is no belief that the owner would consent to the continued use. The cycle offense uses the same wording about the owner’s consent, so a sensible reading is that permission to ride to the shop is not permission to keep the bike for the weekend. A court decides where a real situation falls.
Charging and time limits
- No attempt charge. CPS guidance says offenses under section 12 cannot be charged as an attempt, so there is no “attempted” version of this charge.
- Time limit. As a general rule, a magistrates’ court may not try an information laid more than six months after the offense, unless another enactment provides otherwise (Magistrates’ Courts Act 1980, section 127). The extra time-limit rules in section 12(4A) of the Theft Act are written for offenses under subsection (1) that involve a mechanically propelled vehicle, which does not describe the pedal-cycle offense. For an ordinary bike, six months is therefore the working assumption; a solicitor can confirm it for a real case.
E-bikes and other gray areas
The definitions in section 12(7) cover “conveyance” and “owner”. They do not define “pedal cycle”. GOV.UK ties the right to ride an electric bike to it being an “electrically assisted pedal cycle” (EAPC), and our guide to e-bike laws in the US, UK and EU explains that category. That is a road-use classification, though, and the Theft Act itself does not say how an e-bike is treated under section 12(5). If an e-bike is involved, especially one that may fall outside the EAPC rules, do not assume the lighter penalties above apply; get legal advice.
Checking the current text
legislation.gov.uk shows section 12 as up to date with all changes known to be in force on or before 9 October 2026, and notes that further changes may come into force later. Its list of changes not yet applied names subsection (7)(a), the definition of “conveyance”, and new sections 26A to 26C elsewhere in the Act; it does not name subsection (5). The CPS page shows updates in September 2022 and September 2024, so treat it as a guide to prosecutors’ approach, and recheck the statute before relying on this page later.
What to do in practice
Ask first. A one-line message to the owner settles the consent question. If you are being questioned about a bike, or have been charged, speak to a solicitor, who can assess your facts. And if your own bike is the one at risk of being taken, locking it properly is the practical protection: see how to lock your bike so it won’t get stolen and our roundup of commuter bike locks.
