class=\"dw-lede\"\u003eThe HKM-7551571 is a electric mountain bike built around a 1000 W brushless rear hub drawing on a 48 V 18 Ah pack (864 Wh of Panasonic-format lithium). Three chainrings and a 7-speed cassette give 21 Shimano gear combinations, which is far wider than the single-ring setups most e-bikes ship with and lets you pedal usefully at 5 mph or 28 mph. Braking is handled by hydraulic disc brakes, front and rear from Tektro, the drivetrain is a 21-Speed Shimano unit, and the rolling stock is 26 x 4.0 in CST rubber on 26 in double-wall alloy rims. Suspension is hydraulic suspension fork with lockout, and the frame is aluminum alloy hardtail with a triple chainring crankset rated for 330 lb (150 kg) of rider and cargo.\u003c\/p\u003e\n\u003cdiv

class=\"dw-prose\"\u003e\n\u003cp\u003eThe HKM-7551571 is electric mountain bike. A genuine 21-Speed Shimano drivetrain rather than a token 7-speed. Mountain-bike geometry means a longer front centre, a slacker head angle and a lower bottom bracket than a city frame. In practice the bike feels calm when the front wheel drops into a hole and it takes a deliberate input to steer, which is what you want when the surface is loose and the speed is up.\u003c\/p\u003e\n\u003cp\u003ePower comes from a 1000 W brushless rear hub with a 1400 W short-duration peak, fed by a 48 V 18 Ah pack holding 864 Wh of Panasonic-format lithium. Peak torque at the wheel is quoted at 80 N.m, and the drive is rated to pull a gradient of roughly 30 degrees with a solo rider aboard. The 21-Speed Shimano drivetrain lets you add your own effort across the whole speed range rather than sitting on the throttle.\u003c\/p\u003e\n\u003cp\u003eQuoted range is 31-50 mi (50-80 km), and the spread is wide because the bike adapts to how it is ridden. Throttle-only riding at the top of the speed range lands near the bottom of that band; moderate pedal assist on rolling terrain lands in the middle; light assist on flat ground with correct tyre pressure reaches the upper figure. Cold below 40 F (4 C), soft tyres, headwinds and a heavy load all pull the number down, and all of it comes back when conditions improve.\u003c\/p\u003e\n\u003cp\u003eContact with the ground is through 26 x 4.0 in CST tyres on 26 in double-wall alloy rims, and suspension is hydraulic suspension fork with lockout. Stopping is by hydraulic disc brakes, front and rear supplied by Tektro. Kerb weight is about 72 lb (33 kg) with the pack fitted, and the frame carries a combined rider-and-cargo rating of 330 lb (150 kg). It suits long mixed rides where the battery is treated as a reserve and the legs do a real share of the work.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"dw-sec reveal\"\u003e\u003ch2 class=\"dw-sec-title\"\u003eKey Features\u003c\/h2\u003e\n\u003cdiv class=\"dw-feat\"\u003e\n\u003cdiv class=\"dw-fcard\"\u003e\n\u003cspan class=\"dw-ico\" style=\"width:22px;height:22px\" aria-hidden=\"true\"\u003e\u003csvg viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2.0\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003ccircle cx=\"12\" cy=\"12\" r=\"8.8\"\u003e\u003c\/circle\u003e\u003cpath d=\"M20.8 12L23 12M18.22 18.22L19.78 19.78M12 20.8L12 23M5.78 18.22L4.22 19.78M3.2 12L1 12M5.78 5.78L4.22 4.22M12 3.2L12 1M18.22 5.78L19.78 4.22\"\u003e\u003c\/path\u003e\u003ccircle cx=\"12\" cy=\"12\" r=\"3.4\"\u003e\u003c\/circle\u003e\u003ccircle cx=\"12\" cy=\"12\" r=\"1.2\" fill=\"currentColor\" stroke=\"none\"\u003e\u003c\/circle\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003cdiv class=\"dw-fbody\"\u003e\n\u003cdiv class=\"dw-ftitle\"\u003e1000 W Brushless Hub Motor\u003c\/div\u003e\n\u003cp\u003eA brushless rear hub delivers a quoted 80 N.m of torque at the wheel, with a 1400 W short-duration peak available for standing starts and short ramps.

Cells are Panasonic-format lithium and the assembly is managed by a battery management system that balances the cells on every charge and isolates the pack on over-current, over-temperature or under-voltage.\u003c\/p\u003e\n\u003cp\u003eReal-world range of 31-50 mi (50-80 km) depends on four variables far more than any others: how much you pedal, total loaded weight, tyre pressure and gradient. Throttle-only riding near 31 mph sits at the bottom of the band. Moderate assist on rolling ground sits in the middle. Light assist on flat ground with tyres at the upper end of their pressure range reaches the top figure.
