What Does an E-Bike Conversion Really Cost?

A conversion usually costs between about EUR 450 and 2,000, depending on which kit you buy and what the bike still needs. The kit with battery is the biggest item at EUR 400 to 1,700. Brakes, tools and small parts come on top. A new e-bike costs about EUR 2,500 on average. All prices are orientation only, as of November 2026, without guarantee.

The cost items

Add up the ranges and you get roughly EUR 420 to 2,060. For most people the middle lies at EUR 800 to 1,200. These are rules of thumb, not a quote.

The kit: where the range comes from

The price range for the kit comes from motor type, sensor and battery. Rough guide values from our planning:

The difference comes from the sensor (cadence is cheap, torque costs more), cell quality in the battery and where the dealer is based. More on the types under motor types.

If you are looking for systems from around EUR 500, you will find them, as netzwelt reports. Below that, support and quality get thin.

Three budget tiers

Buying at the very bottom means saving on battery and support. That often comes back to bite you. More on the battery under battery.

What people tend to forget

• Brakes: More weight and speed need good brakes. Hydraulic disc brakes are best, and the cost belongs in the budget. See brakes.
• Tools: A lockring tool and a crank puller are often missing. See tools.
• Wear parts: Chain, pads, tyres. New parts first, see frame and weight.
• Workshop: If you do not do the work yourself, you pay an hourly rate. We have no reliable figure for that yet; it will be set provisionally.

Conversion, used or new

A new e-bike costs about EUR 2,500 on average (Upway). For that you get a warranty, matched components and certainty about the legal status. A conversion is worth it when:

• your bike is good and you want to keep it,
• the frame is suitable (steel or aluminium),
• you can do the work yourself or have a conversion-friendly workshop,
• the extra costs stay small.

A used e-bike is a real alternative if your bike is a problem case: carbon, a coaster brake on a Dutch-style frame, or worn-out components. We do not yet have figures for used e-bikes; they are still being determined. If the conversion cost comes close to the price of a good used bike, leave it and buy used.

Your own calculation

With the cost calculator you put together kit, brakes, tools and small parts for your bike and see where you end up compared with new and used.

How reliable is this?

The kit range of EUR 400 to 1,700 and the comparison price of about EUR 2,500 come from the linked sources. Costs for brakes, tools and small parts and the budget tiers are assumptions that Fabio is still checking. Prices are orientation only, as of November 2026, without guarantee.
