Stellar comes with bright front and rear lights, so you will always stay visible. You also never have to worry about forgetting the lights home or about them getting stolen.
Stellar has Shimano hydraulic disc brakes that are designed for high braking power, reliability and easy maintenance.
City streets often have broken bottles and sharp stones that create punctures and flat tyres. To remove that worry, Stellar comes with lightweight Continental puncture-protected tyres.
You have a window into your bike via Ampler mobile app, where you can customise the motor assist settings, track your rides, navigate with built-in maps, and receive over-the-air updates.
