Buying guides
Electric bike conversion kit or complete e-bike?
A conversion lets you retain a bicycle you already know and like, provided it is suitable for the proposed system. A complete e-bike gives you a defined bicycle, battery and charger configuration from the start. Compare the whole project rather than a kit's headline price against the price of a complete bicycle.
TXED manufactures complete electric bikes. This guide explains the decision between those two routes; it does not offer a conversion kit for a TXED model.
When retaining your bicycle has value
You may already have a comfortable fit, accessories arranged for your daily route and a bicycle in good condition. Those are practical reasons to explore a conversion. The first step is a suitability assessment for that particular bicycle, including its structure, brakes, wheels and the additional equipment and weight.
A kit is fitted to a donor bicycle that was originally supplied in another configuration. The Department for Transport's conversion guidance explains why this assessment and the compatibility of the electrical parts matter. It generally regards buying a complete e-cycle as the safer option.
Compare the full scope
| Item | Conversion project | Complete e-bike |
|---|---|---|
| Bicycle | Existing bike, with a condition and suitability assessment. | A defined model and configuration to compare before ordering. |
| Electrical system | Kit, battery, charger and their documented compatibility. | Specified included equipment; confirm the chosen version. |
| Work before riding | Professional installation and any required mechanical work. | The supplied final-assembly and setup process. |
| Budget | Kit plus battery/charger if separate, installation, donor-bike work and delivery. | Bike price, delivery where applicable, setup help if needed and accessories. |
| Support | Clear responsibilities for the kit, donor bicycle and installation. | Model support and the seller's published warranty and service arrangements. |
Ask for a written conversion proposal
Give the installer the exact donor-bike model, photographs and intended use. Request the proposed kit and battery identification, fitting requirements, instructions, full cost and responsibility for the completed work. Include any changes needed to the bicycle rather than discovering them after buying the electrical parts.
OPSS recommends using a competent professional for a conversion. A correctly specified collection of parts and a competent installation are separate parts of the same decision.
Keep the intended use clear
For use as an EAPC in Great Britain, the complete configuration must meet the relevant requirements, including pedals, a maximum continuous motor rating of 250W and assistance cutting off at 15.5mph. A “250W kit” label alone leaves other requirements to confirm. Read the UK e-bike rules guide for the full context.
If you prefer to compare complete configurations, start with Trail and Maverick. Both include their battery and original charger, with final setup still required under the supplied instructions. Compare fit, weight, storage and your usual route alongside the electrical specification.
