Magura MT5e, MT7, and Gustav Brakes: Why High-Power E-Bikes Need Serious Stopping Power
Magura MT5e, MT7, and Gustav Brakes: Why High-Power E-Bikes Need Serious Stopping Power
Why these brakes? Magura MT5e, MT7 Pro, and Gustav Pro are the strongest hydraulic disc brakes HPC fits to high-power e-bikes because they deliver multi-piston, e-bike-rated stopping force built for speed and weight. The MT5e is the quad-piston workhorse, the MT7 Pro adds a 1-finger HC blade for sharper control, and the Gustav Pro gives maximum stopping power for the heaviest, fastest builds and e-moto like Talaria and Sur-Ron.
At HPC, we build e-bikes that hit 50, 60, and beyond. That number on the speedometer is only half the story — the other half is whether you can shed that speed, on demand, every single time. You cannot responsibly sell a 50–60+ mph e-bike without an equally serious braking story behind it. Motor power is easy to add; the real engineering discipline is making sure the bike stops as confidently as it accelerates.
Speed and mass are the two variables that matter. A high-power e-bike carries far more kinetic energy than a pedal bike — energy that scales with the square of speed. Double the speed and you roughly quadruple the energy your brakes have to convert to heat. That is why we standardize on Magura's e-bike-rated hydraulic systems instead of trail-bike hardware that was never designed for these loads. Below is how the three tiers break down and which HPC build each one belongs on.
Why Braking Is a High-Speed Problem, Not an Afterthought
Three things separate a brake that survives high-power e-bike duty from one that fades: piston count, rotor size, and heat management. More pistons mean more even pad pressure and more clamping force. Larger rotors give a longer lever arm and more surface area to dump heat. And a firm, modulated lever means you can meter that force precisely instead of grabbing all of it at once. Magura engineers all three around e-bike weight and speed — which is exactly why they anchor every high-speed HPC build.
Magura MT5e — The Quad-Piston Workhorse
Magura MT5e Brake Kit
The MT5e is our baseline for serious stopping power — a genuine 4-piston hydraulic caliper packaged specifically for e-bikes. What sets the "e" version apart is the integrated e-brake lever with a motor cutoff switch and Higo plug, so squeezing the lever cuts throttle power at the same instant it applies the brakes. It ships with a 2200mm hose, and HPC offers custom-length service to route it cleanly on any frame.
Four pistons deliver strong, even clamping force with reliable modulation, and the MT5e's simplicity and value make it the workhorse we're happy to run on the majority of our builds. If you want a proven, no-drama brake that just works at speed, this is where the lineup starts.

Magura MT7 Pro — 1-Finger HC Performance
Magura MT7 Pro Quad-Piston Brake
The MT7 Pro keeps the proven 4-piston caliper platform but steps up the control side of the equation with a premium 1-finger HC aluminum blade. That blade geometry is the point: it's engineered so a single finger delivers full, confident braking force, freeing the rest of your hand to keep a firm grip on the bar at speed. The result is sharper modulation and a more planted, race-inspired feel under hard braking.
This is the upgrade for riders who push harder — aggressive trail and off-road use, spirited high-speed street riding, or anyone who simply wants the best lever feel Magura's MT line offers. Same 2200mm hose and custom-length service as the MT5e, with a meaningful jump in refinement at the lever.

Magura Gustav Pro — Maximum Stopping Power
Magura Gustav Pro Brake
The Gustav Pro is the heavy hitter. This is Magura's most powerful hydraulic brake, purpose-built for the heaviest and fastest machines — the kind of high-power e-bikes and light e-moto platforms like Talaria and Sur-Ron that carry serious mass and hit serious speed. When a build outgrows what a standard MTB-derived brake can handle, the Gustav is the answer.
It's engineered around larger rotors and a bigger 4-piston caliper to generate more raw clamping force and, just as importantly, to manage the heat that comes from repeatedly hauling down a heavy bike from high speed without fading. If you're building at the top of the power and speed ladder — or converting a Sur-Ron or Talaria to brakes that actually match the motor — this is the tier you want.

- Rotor pairingLarge rotors (up to 220mm)
- StrengthHighest clamping force + heat capacity

Which Magura Brake Is Right for Your Build?
| Model | Pistons | Lever / Blade | Rotor | Best For |
|---|---|---|---|---|
| MT5e | 4-piston | E-brake w/ motor cutoff | 203mm | Core workhorse for most high-power builds |
| MT7 Pro | 4-piston | 1-finger HC aluminum | 203mm+ | Performance upgrade, aggressive riding |
| Gustav Pro | 4-piston (max power) | Performance HC | Up to 220mm | Heaviest/fastest builds, Talaria & Sur-Ron |
Simple rule of thumb: start with the MT5e for a rock-solid standard, step up to the MT7 Pro when you want a sharper 1-finger lever and more refinement, and go Gustav Pro when the build is heavy, fast, or e-moto and you need every bit of stopping power Magura makes.
Speed You Can Trust Means Brakes You Can Trust
Anybody can bolt a bigger motor onto a bike. Building one that safely does 50–60+ mph — and stops like it — is the harder, more important job. Every HPC build is spec'd so the brakes match the power, which is why Magura's e-bike-rated hydraulics are our standard rather than an upsell. Not sure which tier fits your bike, weight, or riding?

Frequently Asked Questions
Is the Magura MT5e good enough for a fast e-bike?
Yes. The MT5e is a true 4-piston hydraulic brake with an integrated motor-cutoff lever, and it's our standard workhorse across most high-power HPC builds. It offers strong, reliable stopping power and excellent value, which is why it anchors the lineup.
What's the difference between the MT5e and the MT7 Pro?
Both use a 4-piston caliper. The MT7 Pro's key upgrade is its premium 1-finger HC aluminum blade, which gives sharper modulation and full braking force from a single finger — a noticeable refinement for aggressive and high-speed riders.
Which brake should I use on a Sur-Ron or Talaria?
The Gustav Pro. It's Magura's maximum-power brake, engineered with larger rotors and extra heat capacity for the weight and speed of e-moto platforms like Sur-Ron and Talaria, as well as the heaviest, fastest e-bike builds.
