What range can you expect from the Randride YG90B?

Randride lists roughly 40-50 km in electric-only riding and up to 80-90 km with pedal assist, depending on terrain, rider weight and assist level.

What is the difference between the 27.5-inch and 29-inch YG90B versions?

Both versions use the same 48V 17Ah removable battery and 1000W peak drive setup, but they run different CST tyre sizes. The 27.5 x 2.4 setup feels a little more agile, while the 29 x 2.1 version rolls more smoothly over rough ground and longer trail sections.

Is the YG90B suitable for rougher terrain?

Yes. With dual suspension, hydraulic brakes and all-terrain CST tyres, the YG90B is better suited to gravel, mixed surfaces and uneven tracks than a basic commuter e-bike.

How long does the YG90B battery take to charge?

Third-party YG90B spec listings put charging time at around 7 to 8 hours for the 48V 17Ah battery. In practice, an overnight charge is the safest assumption before a full day's riding.

Is the Randride YG90B easy to assemble?

The Randride YG90B comes mostly assembled and only minor things need to be assembled. This should not take longer than 20-30 minutes to do.

Is the Randride YG90B water resistant?

The Randride YG90B is water-resistant and suitable for riding in light to moderate rain. It is not fully waterproof and should not be submerged. Short term, your product can get a little wet and be in the rain, but any long-term exposure can cause serious problems.

Is the Randride YG90B Electric Mountain Bike road legal?

No — this model is designed for off-road/private land use. It isn’t intended for public roads, cycle lanes, or pavements. Use on private land with the landowner’s permission.

Description

Quick Summary
The Randride YG90B is a high-power, full-suspension electric mountain bike designed for both off-road adventure and heavier duty use. With a 1000 W motor and a 48 V/17 Ah battery it offers strong performance, while the 27.5″ all-terrain tyres and full suspension help you tackle rougher surfaces with more confidence.

Smooth Power Delivery
With the 1000W motor, the YG90B delivers strong torque and high top speed (up to ~45 km/h). The 21-speed Shimano gearing allows the rider to shift appropriately through terrain and adjust cadence if pedalling.

Comfort & Control
The full suspension setup (front fork + rear shock) and 27.5″×2.4″ CST tyres combine for a ride that absorbs bumps and gives better control over mixed terrain. The hydraulic disc brakes offer better stopping performance than mechanical options, important when riding at speed or downhill.

Smart Battery System
The removable (in some listings) 48 V 17 Ah battery delivers substantial capacity (~816 Wh) by some estimates. Real-world tests indicate ~45 km in mixed/off-road use in electric mode for a ~80 kg rider, though assist mode figures of 70-90 km are quoted by the manufacturer.

Tech You Can Trust
The YG90B features a well-specified Shimano 21-speed gearset, hydraulic disc brakes, an aluminium frame (which resists rust and keeps weight down), and a colour LCD display that gives you ride data.

Built for Everyday Use
Whether you're commuting or going off-road, this bike offers strong capability. The 27.5″ wheels strike a balance between agility and stability, the full-suspension aids comfort across rough ground, and the high capacity battery plus high-power motor make it suitable for heavier riders or longer rides.
