Design & Build Quality
The OKAI Foldable Class 2 E-Bike showcases clean engineering and thoughtful ergonomics. The 6061 aluminum alloy frame combines strength and lightness, offering both durability and portability.
Its step-through folding frame design makes it extremely easy to mount, especially for shorter riders or those who prefer convenience. The folding mechanism is secure and smooth — allowing you to collapse the bike in under 20 seconds for transport or storage in tight spaces like car trunks, apartments, or offices.
The matte finish with subtle OKAI branding gives it a polished, modern aesthetic. Build tolerances feel tight, hinges solid, and no rattle is noticed during riding. Despite its foldability, the bike feels firm and stable even at high speeds.
The rear cargo rack and front suspension fork make it functional for daily use — carrying groceries, work gear, or even light travel bags without compromising comfort.
Motor Performance – 500W Rated Power (20 MPH Top Speed)
The OKAI e-bike uses a 500W brushless rear hub motor that peaks around 750W, offering smooth and consistent acceleration.
- Top Speed: 20 MPH (Class 2 legal limit)
- Torque: Ample for moderate hill climbs and stop-and-go traffic
- Throttle Mode: Instant acceleration at the twist of a grip
- Pedal Assist Mode (PAS): Natural, progressive power output
Acceleration is quick yet controlled, making it ideal for commuting and neighborhood cruising. The bike’s torque management system provides enough power for urban inclines while keeping the experience comfortable and predictable.
You can switch between throttle-only, pedal assist, or manual riding depending on terrain and preference.
Battery & Range
Powering the motor is a 48V 12.5Ah (approx. 600Wh) lithium-ion battery, neatly integrated into the bike’s downtube. The removable, lockable design adds convenience and security — charge it on or off the bike.
- Range (Pedal Assist): Up to 59 miles per charge
- Range (Throttle-Only): Around 35–40 miles
- Charging Time: 5–6 hours
The Battery Management System (BMS) protects against over-charging, over-current, and thermal issues. OKAI’s UL-certified power system meets the highest safety standards, giving riders peace of mind.
For a commuter or casual rider, that 50+ mile range translates into several days of use per charge.
Drivetrain & Riding Modes
The OKAI features a reliable Shimano 7-speed drivetrain, allowing smooth shifting across a range of terrains.
With three pedal assist levels plus full-throttle and manual options, you can customize your ride:
- PAS 1 (Eco): Conserves battery for long rides
- PAS 2 (Normal): Balanced assist for mixed terrain
- PAS 3 (Sport): Strong torque for hills or quick commutes
The shifting is crisp and intuitive, while the chainring and derailleur are well protected by a guard — minimizing maintenance needs.
Comfort & Suspension
OKAI designs for rider comfort. The front suspension fork effectively absorbs shocks from uneven roads, speed bumps, or gravel paths. Combined with 20″ x 4″ fat tires, the ride remains smooth and stable across different surfaces.
The wide ergonomic saddle and upright handlebar posture reduce back strain during long rides. The fat tires not only provide traction but also act as natural shock absorbers — ideal for mixed-terrain travel or city commuting.
Even after extended rides, the bike feels comfortable, balanced, and fatigue-free.
Braking System
The bike is equipped with mechanical disc brakes on both front and rear wheels. The braking performance is consistent and dependable, providing confident stopping in wet or dry conditions.
Each brake lever integrates motor cutoff sensors, which instantly disengage power to the motor when braking — ensuring safety and reducing wear.
For a commuter-class e-bike, the braking system performs exceptionally well, with progressive modulation and strong stopping force.
Lighting & Safety Features
Safety is a core focus for OKAI. The e-bike includes a powerful LED headlight for night riding, a rear brake light, and reflective tire sidewalls to improve visibility from all angles.
The electrical system is UL-certified, meaning the battery, motor, and charger meet rigorous safety and durability standards.
This certification — now increasingly mandatory for e-bikes in the U.S. — ensures fire and electrical protection compliance for urban environments.
Display & Controls
A clear LCD display mounted on the handlebar provides all the essential ride metrics:
- Current and average speed
- Trip distance and odometer
- Battery level
- PAS level and throttle indicator
- Headlight status
The screen is backlit for visibility during day or night, and the control pad near the left grip allows one-hand access to all functions.
Portability & Practicality
Weighing around 63 lbs, the OKAI folds compactly for convenient transport and storage. The frame locks securely in both folded and unfolded positions, and once folded, it fits easily into SUVs or tight apartment corners.
The rear rack and fenders enhance practicality, making it a genuine daily-use commuter bike — not just a recreational model.
