Magura Ø220 mm Brake Disc – Dovetail Interlink, 6-Bolt IS

The Magura Ø220 mm brake disc is a two-piece steel rotor built for electric motorcycles and heavy e-bike platforms. It fits SurRon, Talaria, E Ride Pro, 79 Bike, Zbike and E-TMX machines. Moreover, it works with E-MTB, S-Pedelec, classic MTB, city and gravel setups. The mounting standard is 6-bolt (IS).

At the heart of the rotor sits patented Dovetail Interlink Technology. The outer braking ring locks mechanically into the inner carrier ring. Instead of rivets or adhesive, a dovetail joint holds the two halves together. Consequently, the assembly stays rigid even under heavy thermal load.

Magura is a German brake and hydraulics manufacturer founded in 1893 in Bad Urach. That engineering background matters here. This rotor is built for the mass and speed of e-moto conversions, not only for pedal-powered bikes. Riders who brake hard and often will notice the difference on long descents.

Key Benefits

• Dovetail Interlink Technology – the outer braking ring is mechanically locked into the inner ring by a dovetail joint.
• High rigidity – the solid two-piece construction reduces vibration and the spongy pumping feel at the lever.
• Maximum braking torque – the Ø220 mm diameter shortens stopping distance compared to 180 mm and 203 mm discs.
• Even heat distribution – the larger surface area reduces brake fade caused by overheating.
• Precise modulation – braking force stays smooth and dosable through long descents.
• Wear-resistant steel – the steel construction handles abrasion and sustained high temperatures.
• Longer service life – lower operating temperatures protect both the pads and the rotor itself.
• Built for heavy loads – designed for the extra mass and speed of E-platforms and cargo riding.

Who Is This Rotor For?

This disc suits electric motorcycles first and foremost. Compatible models include SurRon, Talaria, E Ride Pro, 79 Bike, Zbike and E-TMX. In every one of these cases, matching adapters are required. Original systems on these machines are usually specified for a smaller rotor diameter.

Beyond e-moto, the rotor fits E-MTB and S-Pedelec class electric bicycles. Enduro and trail riders choose it as well. City cyclists carrying extra weight benefit from the added stopping power. On classic MTB, city and gravel bikes it performs without issue, provided frame and fork specifications allow a 220 mm diameter.

Above all, this disc earns its place where braking is frequent and hard. Think long descents, e-moto conversions and rides with additional cargo. Because Ø220 mm exceeds standard MTB sizes of 160-203 mm, a Magura QM 46 adapter is often necessary when the caliper is set up for a 180 or 203 mm rotor. Check fork and frame clearance before ordering.

Technical Specifications

Why Choose This Magura Rotor?

The first difference is the construction. Rather than a riveted or bonded joint, this rotor uses a mechanical dovetail lock between the outer braking ring and the inner ring. As a result, the connection stays rigid under high thermal stress. Riveted rotors can loosen over time; this one is designed to resist that.

The second difference is diameter. At 220 mm, it sits above the usual 203 mm ceiling. Therefore, the same lever force generates greater braking torque. In practice that means a shorter stopping distance. It also means more control on heavier E-platforms carrying real speed.

The third difference is experience. Magura builds hydraulic brake systems for both the bicycle and motorcycle industries. This rotor size is therefore matched to genuine SurRon and Talaria class loads. It is not a bicycle part stretched to fit a heavier machine.

Frequently Asked Questions

Will this rotor fit my SurRon or Talaria?

• Yes, the Ø220 mm disc is designed for SurRon, Talaria, E Ride Pro, 79 Bike, Zbike and E-TMX.
• An appropriate adapter is required, since original systems are usually built around a smaller diameter.

Do I need the Magura QM 46 adapter?

• You will often need it when the caliper is positioned for a 180 or 203 mm disc.
• The QM 46 adapter is sold separately and is not included with the rotor.

Can I use this on a regular MTB, city or gravel bike?

• Yes, provided the frame and fork specifications allow a 220 mm diameter.
• Standard MTB sizes run from 160 to 203 mm, so clearance must be verified first.

What mounting standard does it use?

• The rotor uses the 6-bolt (IS) mounting interface.
• Mounting bolts are purchased separately.

What is Dovetail Interlink Technology?

• It is a patented joint where the outer braking ring locks mechanically into the inner ring.
• The dovetail shape replaces rivets or adhesive, keeping the disc rigid when hot.

Does a bigger rotor really stop better?

• Yes, Ø220 mm produces more braking torque than 180 mm and 203 mm discs at the same lever force.
• The larger surface also spreads heat more evenly, which reduces fade.

Is it suitable for e-bike conversions with cargo?

• Yes, it is built for the higher mass and speed found on E-platforms.
• Cooler running temperatures extend the life of both pads and rotor.

How many discs are in the package?

• One Ø220 mm rotor is included.
• Adapters and bolts are ordered separately.

For riders upgrading an e-moto conversion or an E-MTB, the Magura Ø220 mm brake disc delivers more torque, better heat control and a firmer lever feel. Confirm your fork and frame clearance, add the correct adapter, and this German-engineered rotor will handle the hardest descents your machine can find.
