The Juiced HyperScrambler 2 is an electric bicycle (e-bike) designed for both on-road and off-road use, offering a blend of traditional cycling with electric motor assistance. It features a robust design with a focus on performance, safety, and user-friendly operation.
Function Description:
The HyperScrambler 2 operates similarly to a conventional bicycle but incorporates an electric motor to provide a boost when desired. It can be ridden using pedal power alone or in combination with the electric motor, which is powered by an onboard rechargeable lithium battery pack. The e-bike's controller regulates the power sent from the battery pack to the motor, allowing for variable levels of assistance. The throttle, located on the right handlebar, enables the rider to control the bike's speed without pedaling. The gear shifter, on the left handlebar, allows for manual adjustment of the pedaling ratio to suit different riding conditions, such as starting from a stop, climbing hills, or riding at speed. The braking system consists of front and rear disc brakes, which include an electrical switch that cuts power to the motor when engaged, preventing unintentional acceleration during braking. The e-bike also features an LCD display that provides essential information about the bike's status and allows for control of various functions.
Important Technical Specifications:

- Headlight: 1,050 lumens.
- Tires: 20 in. x 4.25 in. wide (inflate to psi indicated on tire).
- Weight Capacity: 275 lbs.
- Fuses: Two replaceable 30-amp fuses for electronics protection.
- Motor: Electric motor built into the hub of the rear wheel.
- Controller: Located under the seat, regulates power to the motor.
- Display: LCD display showing battery pack voltage, charge state, speed, trip distance, assist level, and other metrics.
- USB Port: Located on the left-side handlebar for charging devices.
Usage Features:
- Turning On/Off: The e-bike is turned on by pressing the battery power button on both batteries and then inserting and turning the ignition key switch. It is turned off by turning the key and removing it, then pressing both battery power buttons. An automatic shutoff feature conserves power after a preset period of inactivity.
- Pedal Assist Control System (Pedelec): This system uses sensors to measure torque and cadence, generating power based on pedaling input. Riders can select from various assist levels (0, ECO, 1, 2, 3, S, R) using "+" and "-" buttons on the LCD display. Level "0" disables pedal assist.
- Throttle Operation: The throttle allows for riding without pedaling. It is controlled by rotating the grip on the right handlebar.
- Headlight and Backlight: The halo headlight automatically turns on when the bike is powered on. It can be turned off by pressing and holding the "assist up" button for 2 seconds. The full headlight is controlled by a combo switch on the left handlebar. The display backlight also activates with the headlight.
- Turn Signals: Controlled by a switch below the headlight button on the left handlebar.
- Walk Mode: Activated by pushing and holding the "assist down" button for 2 seconds, this mode provides motor assistance at walking speed for pushing the bike uphill.
- Cruise Control Function: Activated by pushing and holding the "assist down" button for 2 seconds at a desired speed. It maintains the speed without continuous throttle or pedal input, with a maximum controllable speed of 20 mph.
- Advanced Display Screen: Provides expanded real-time data including battery voltage, real-time power (watts), real-time amps, amp-hours, watt-hours, controller temperature, and trip distance.
- Adjustable Parameters: Settings like unit (mph/kmh), speed limit, backlight brightness, wheel size, "power off" delay, NDW (pedal assist level limiter), and torque sensor activation can be adjusted via the setup menu.
- Error Codes: The LCD display can show error codes for self-diagnosis of faults in the electronics system, such as throttle faults, low/over voltage protection, motor hall/phase line faults, temperature sensor faults, current sensor faults, speed sensor faults, and communication faults.
Maintenance Features:
- Battery Charging: The battery pack can be charged while installed on the bike or removed. The charger indicates charging status (red for charging, green for fully charged) and automatically stops charging when full. It's recommended to charge after every ride and at least once a month to prevent permanent capacity loss.
- Brakes: The hydraulic disc brakes require periodic inspection for wear and tear. A "bedding-in" period of 40-50 full stops is needed for new brakes to reach full grip capacity.
- Suspension Adjustment: Forks and rear shocks can be adjusted for a softer or stiffer ride by rotating pre-load and compression knobs. Adjustments should be made in small increments and tested in a hazard-free area.
- Tire Pressure: Maintain proper tire inflation (30-35 psi) for optimal range and performance.
- General Inspection: Regularly check that hardware is fastened, tires are inflated, brakes operate, handlebars are secured, and cable connections are tight.
- Cleaning: Regular cleaning of the e-bike is recommended.
- Professional Service: For complex repairs, hydraulic brake service, or issues with mineral oil cups, a trained mechanic or authorized Juiced Bikes dealer should be consulted.
- Warranty: The product comes with a limited warranty covering manufacturing defects, with specific periods for battery packs, electronic components, bicycle frames, and mechanical components. It emphasizes proper use, maintenance, and authorized repairs to maintain warranty validity.
