This is the real Go 5 Ultra, and We tested it for you
This is the production Go 5 Ultra — the real bike that you're getting, not a prototype anymore. We took it out for a full day and filmed the whole thing.
Dual-Mode Charging
Ride Mode
Power While You Ride
While the bike is moving, solar power helps drive the motor, reducing the amount of energy drawn from the battery.
Park Mode
Recharge While You Park
When the bike is parked in sunlight, solar power is redirected to recharge the battery.
PERFORMANCE
Performance Built Around the Ride
From precise electronic shifting to responsive suspension and hydraulic braking, the Go5 Ultra is designed to deliver a smoother, more controlled riding experience across changing terrain.
ELECTRONIC SHIFTING
Shifting That Keeps Up
The electronic shifting system enables precise, button-controlled gear changes for smooth transitions during acceleration, climbing and cruising.
5 Pedal-Assist Modes
Power That Adapts to Every Ride
BRAKING CONTROL
Confident, Controlled Braking
Hydraulic disc brakes with 180 mm rotors at both the front and rear provide smooth, responsive braking control across changing road and riding conditions.
DUAL SUSPENSION COMFORT
110 mm Up Front. 35 mm Under the Saddle.
A 110 mm adjustable air-suspension fork absorbs larger bumps and uneven terrain, while the suspension seatpost provides 35 mm of travel to help reduce vibration beneath the rider. Together, they deliver a smoother, more controlled ride across changing surfaces.
SECURITY
Double Protection for Every Ride
Combine physical locking with connected smart-security features to help protect your Go5 when it is parked.
PHYSICAL CONNECTEDPHYSICAL PROTECTION
Three Ways to Lock Your Go5
Use a high-quality physical lock whenever your bicycle is left unattended.
Watch Locking Guide
WAY 01
Secure the Frame
Pass a high-quality chain lock through the main frame and secure it to a sturdy, permitted fixed object.
WAY 02
Immobilize the Crank
Route the chain through the crank or pedal area to help prevent the bicycle from being ridden away.
WAY 03
Add a Disc-Brake Lock
Fit a compatible disc-brake lock to the brake rotor to prevent the locked wheel from rotating. Always remove it before riding.
Chain locks and disc-brake locks can be selected as optional accessories where available.
CONNECTED SECURITY
Stay Connected to Your Go5
Connected features can help riders monitor the bicycle and respond when unexpected movement is detected.
01
Movement Alerts
When security mode is active, unexpected movement can trigger an alert to help you respond.
02
Location Awareness
Use available connected location tools to check your bicycle's reported position.
03
Added Peace of Mind
Connected security tools add another layer of awareness when your Go5 is parked.
