The manufacturer claims a range of 80–90 km with pedal assistance. Its equipment suits commuting and recreational rides over varied surfaces, but before riding on public roads, check whether the specific version is approved for use and what rules apply.
Motor and speed
The brushless motor has a stated output of 1,000 W and torque of 75 Nm. Higher torque can help when starting off and climbing, although the available pulling power also depends on the gradient, the load on the bike and how much the rider pedals.
The stated maximum speed is up to 45 km/h. This power and speed should not automatically be treated as the specifications of a standard e-bike permitted on every public road. Before riding, check the classification and approval of the specific version and the rules in the country where you intend to use it. Whether the bike can be operated under electric power alone, without pedalling, may also be relevant.
Battery and range
The bike uses a Samsung-type battery rated at 48 V / 17 Ah, giving it a nominal capacity of approximately 816 Wh. The manufacturer provides two estimated ranges:
- 80–90 km with motor assistance, when the rider pedals.
- 40–50 km on electric power alone, without pedalling.
Actual range can vary with the assistance level, terrain, rider and cargo weight, speed, temperature and battery condition. When planning a longer route, it is sensible to leave a reserve, especially if the route is hilly or you expect to use more assistance.
Gears, suspension and brakes
The 21-speed Shimano drivetrain lets riders adjust pedalling effort for climbs and faster stretches. Choosing an appropriate gear can help maintain a comfortable cadence and conserve energy on longer rides.
Front and rear suspension help absorb bumps, particularly on rough roads and away from paved surfaces. Hydraulic disc brakes provide braking and speed control; their effectiveness in practice depends not only on their condition but also on the surface and riding conditions.
Frame, wheels and rack
The frame is made from aluminium alloy, and the stated weight of the complete bike is 28 kg. This may not be a major obstacle while riding, but it is worth considering if you need to carry the bike upstairs or load it onto a car rack.
The 29-inch wheels have 2.1-inch-wide tyres intended for a variety of surfaces, including routes outside the city. A rear aluminium rack provides space for a small load, such as items needed for a daily commute.
Display and controls
A colour LCD display on the handlebars shows speed, battery status and motor assistance level. This lets the rider monitor the remaining energy and adjust assistance to suit the length or difficulty of the route.
The RANDRIDE YG90B-29 combines a powerful motor with suspension, hydraulic brakes and a rack. When considering it, pay particular attention to its weight, the conditions that affect real-world range and the legal classification of the specific version for your intended use.
