A discreet motor inside the Tron- style Emicro’s rear wheel generates a subtle burst of electric power when you scoot beyond 5kph. Three speed modes – Eco, Standard or Sport – increase maximum power output. Regenerative-braking tech not only delivers reassuring control over the ride but also charges the battery. Sensors detect when you’re pointing uphill, increasing the power and torque to keep things moving. If you’re looking for portable, the Emicro’s folding chassis, heightadjustable bars and 7.5kg weight make it ideal for stowing in your car’s boot or under your desk.
