Why 80% of riders regret sticking with cable brakes — and how NUTT hydraulic changes everything.
Quick answers to the most common questions about NUTT hydraulic brake systems.
Yes, the NUTT A5-D is designed as a direct bolt-on replacement for popular electric scooters like Dualtron, Zero, KuKirin, and Booster ES3. It comes with a plug-and-play design, so you won't need any extra modifications or adapters for a standard installation.
Yes — but the OOTD T10 needs one small extra part. Fit a 3mm spacer between the motor and the brake rotor. This pushes the rotor and the caliper bracket outwards as a single unit, giving the A5-D the clearance it needs to sit squarely over the rotor.
It's very straightforward. The ergonomic design includes a simple reach adjustment mechanism. You can easily bring the brake lever closer to the handlebar without any tools, making it comfortable for riders with smaller hands and reducing finger fatigue on longer commutes.
Bleeding hydraulic brakes can be messy. Our quick oil bleed system simplifies maintenance by making it much easier to remove air bubbles from the system, ensuring consistent braking performance. It's a cleaner, faster process that you can even do at home.
We understand scooters come in different sizes. The A5-D offers custom tube length options, typically 1300mm for the front and 2200mm for the rear, so you can select the length that perfectly fits your specific scooter model to avoid messy routing.
