Buying Randride online?
As with a car, ask where you can take your ride if it needs a repair.
Be cautious if a seller can’t give you a local workshop address, especially if they ship from overseas or dropship.
Check with the brand that the seller is authorised and ask who handles warranty repairs.

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.
