Cockpit and Controls

Left Side

• Double locking grip with gel-formed palm rest
• Front brake lever
• Thumb throttle
• Control pad with power, plus, minus, walk mode, and turn signal buttons (turn signals not installed)

Right Side

• Rear brake lever
• Shimano gear shifter (thumb downshift, index finger upshift)
• Bell for safety alerts

Display and Settings

• Full-color display with adjustable brightness and multiple readouts: max speed, average speed, odometer, trip mileage
• Ability to switch between miles and kilometers
• Programmable throttle and pedal assist speed limits (up to around 33 mph)
• Throttle modes: free mode (throttle works stationary) and safe mode (throttle only works while moving)
• Fault check, password protection, firmware version display

Performance Testing

• Throttle speed depends on gear, not pedal assist level
• Pedal assist works in torque mode below $20\text{ mph}$ and switches to cadence mode above $20\text{ mph}$ for easier high-speed pedaling
• Top throttle speed observed was about $20\text{ mph}$ in gear 7 despite setting throttle limit higher
• Pedal assist level 5 allowed speeds up to $30\text{ mph}$

Speedometer Accuracy

• Display speed is about 1 mile per hour higher than GPS reading (e.g., 20.3 mph vs 19.2 mph)
• Maximum recorded top speed during test: 29.6 mph

Comfort and Handling

• Upright riding position with adjustable stem
• Comfortable, plush suspension suitable for long rides
• Effective dual crown fork provides excellent absorption over rough terrain and bridges
• Bike handles well on sharp turns despite its size and weight

Braking Performance

• At $20\text{ mph}$, stopping distance was around 18 ft(excellent)
• At $28\text{ mph}$, braking caused rear wheel hopping and instability, resulting in a longer stopping distance (~$45\text{ ft}$) and less confidence

Walk Mode

• Activated by holding the minus button on the control pad
• Moves bike forward at approximately $2\text{ mph}$ regardless of gear or pedal assist level

Sand Riding Test

• Smooth riding through loose and hard-packed sand using both throttle and pedal assist
• Bike maintained speeds around 9 mph on sand with ease
• Mid drive motor’s power and torque excelled in overcoming loose terrain

Hill Climbing (Hill of Doom)

• Hill grade up to 31° tested
• Throttle alone managed slow ascent (~2 mph)
• Pedal assist levels 3 and above made hill climbing effortless with minimal rider effort
• Lower pedal assist and gear combinations required significant effort and were less successful

Trail and Off-Road Use

• Suitable for gravel, dirt trails, and light off-roading
• Suspension and torque provide smooth, controlled riding
• Not designed for technical single-track mountain biking but good for outdoor exploration, hunting, fishing, or camping access

Battery Life and Range

• Real-world range tested at approximately 28−29 miles on a single charge under mixed conditions including wind, hills, and sand
• Battery indicator uses 10 bars (about 10% per bar), though no exact percentage shown
• Battery and motor remained efficient even under heavy wind resistance
• Ability to ride with one bar of battery remaining and still maintain throttle assist at lower speeds
• Recommended to air tires to maximum PSI to optimize suspension and range

Experience and Final Thoughts

Pros

• Extremely powerful motor with 210 Nm torque for tackling hills and rough terrain
• Smooth and aggressive throttle response uncommon in mid drive eBikes
• Comfortable riding position and plush suspension system
• Versatile with stepthrough and stepover frame options
• Durable components including hydraulic brakes and puncture-resistant tires
• Good range and battery management for this class of eBike
• Useful walk mode and configurable display settings

Cons

• Persistent headlight issue: the front headlight stays on continuously and requires manual disconnection of the battery or unplugging
• Rear brake instability at higher speeds causing wheel hopping and reduced braking confidence
• Small and hard-to-read display text, especially for trip information and battery levels
• Tail light is battery powered and not integrated, which feels less premium for the price point
• Adjustable stem prone to loosening during rides
