At Pro9 Bicycle Studio, performance starts with the smallest components.
Our wheel builds feature high-strength black stainless steel spokes combined with steel spoke ni***es with protective ED coating and premium black finish.
Why does it matter?
✔ High-strength steel construction for demanding e-bike applications
✔ ED coating helps protect against corrosion and rust
✔ Durable black finish for a premium factory look
✔ Stronger and more reliable under high spoke tension
✔ Built to handle the torque of powerful hub motors
Every wheel is hand-built with precision because we believe reliability isn't optional—it's engineered into every spoke, every ni**le, and every wheel we build.
When you're building e-bikes designed to last, every detail counts.
