Cast alloy wheels carry 20 x 4.0 knobby tires, an inverted double-crown fork and a rear coil shock handle the rough ground, and dual hydraulic discs do the stopping. There is a seven-speed cassette, NFC unlock, a round grille headlight with turn signals, a bench seat and a fold for storage. It is listed at 34 to 40 miles and it rides like a small motorbike rather than a mountain bike.\u003c\/p\u003e\n\n\u003cp\u003eThe look is doing a lot of the work here, and it is deliberate: a bench seat rather than a saddle on a post, a round grille lamp, a side plate where a race number would go, and one-piece cast wheels. Very little in this range bothers with a coherent retro theme, and the black-on-black finish is what keeps it from becoming a novelty. The bench changes who buys it: you sit on it rather than over it.\u003c\/p\u003e\n\n\u003cp\u003eUnderneath that it is a 20-inch fat bike with a long wheelbase, a 960Wh pack in the frame and suspension at both ends. That is the honest description: it is not a trail bike in the mountain-bike sense, but it does have the travel and the tire volume to make a fire road or a packed beach into a comfortable ride rather than an endurance test, and the seven-speed cassette lets you turn the pedals on a grade instead of letting the motor do everything.\u003c\/p\u003e\n\n\u003ch2\u003eAt a Glance\u003c\/h2\u003e\n\n\u003cul class=\"hkm-glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak 1500W Hub\u003c\/strong\u003e — 50 Nm, 35 degree climb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e48V 20Ah Pack\u003c\/strong\u003e — 960Wh inside the down tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e34 to 40 Miles\u003c\/strong\u003e — Listed range, 8 to 10 hour charge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25 mph Listed\u003c\/strong\u003e — Poster figure, page says to 37\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7-Speed Drive\u003c\/strong\u003e — Cassette behind the hub motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic Discs\u003c\/strong\u003e — Dual, front and rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Suspension\u003c\/strong\u003e — Inverted fork, rear coil shock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCast Alloy Wheels\u003c\/strong\u003e — 20 x 4.0 knobby, no spokes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNFC Unlock\u003c\/strong\u003e — Card or key, PAS 1 to 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetro Bench Seat\u003c\/strong\u003e — Moped length, fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFolds\u003c\/strong\u003e — For storage, not for a train\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRound Grille Lamp\u003c\/strong\u003e — With turn signals and horn\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRetro Body and Cast Wheels\u003c\/h2\u003e\n\n\u003cp\u003eThe frame is a moped shape in black, with a long bench over the rear wheel and a battery tucked into the down tube. A side plate sits where a race number would go on a flat-track bike, and the round grille headlight finishes the look.\u003c\/p\u003e\n\n\u003cp\u003eThe wheels are cast alloy in one piece, which is the detail that separates this from a generic fat bike. There is no spoke tension to check, nothing to go out of true at the low pressures a four-inch casing wants, and the bead seat holds better when you drop to 8 psi in sand.\u003c\/p\u003e\n\n\u003cp\u003eSuspension is at both ends: an inverted double-crown fork up front and a pair of coil shocks under the rear of the frame. On 20-inch wheels with four inches of tire that is enough to keep the bike from skipping across a washboard track, which is the sort of surface this bike is actually bought for.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eFrame: moped shape, black\u003c\/li\u003e\n\u003cli\u003eBattery: 48V 20Ah, down tube\u003c\/li\u003e\n\u003cli\u003eWheels: cast alloy, 20 in\u003c\/li\u003e\n\u003cli\u003eFork: inverted, double crown\u003c\/li\u003e\n\u003cli\u003eRear: coil shock\u003c\/li\u003e\n\u003cli\u003eBrakes: hydraulic disc, both ends\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFitted as shipped: front and rear fenders, a flat rear rack, the round grille headlight, a small bar bag, a kickstand and the battery keys. Braking is dual hydraulic discs, front and rear, with the hose routed down the fork leg and a motor cut-off at each lever. The bars carry the turn signals, the horn button and the NFC reader, and the pedals are platform type with reflectors.\u003c\/p\u003e\n\n\u003ch2\u003e1500W Hub and the Listed Range\u003c\/h2\u003e\n\n\u003cp\u003ePeak power is 1500W from a single brushless rear hub, with 50 Nm of torque and a listed 35 degree climb. One motor keeps the steering light and leaves one controller to look after, and because it turns a cast 20-inch wheel the torque reaches the tire with less loss than the same unit would manage on a larger rim. The seven-speed cassette behind it means you pedal with the motor rather than against it.\u003c\/p\u003e\n\n\u003cp\u003eThe pack is 48V 20Ah, which works out at 960Wh, and it sits inside the down tube behind a key-locked cover. A full charge runs 8 to 10 hours on the supplied charger through a sealed port, so the bike comes indoors rather than the battery. The poster claims up to 65 miles; plan on 34 to 40, because that larger figure assumes a light rider, flat ground and the lowest assist level.\u003c\/p\u003e\n\n\u003cp\u003eTop speed is listed as 25 mph on the poster and 25 to 37 mph on the product page, and the gap matters. 25 mph is already the Class 3 ceiling in the US; 37 mph is a downwind, full-throttle number that no state allows on a public path. Ride it on private ground or a trail where the limit does not apply, and check local rules before using the top of that range anywhere else.\u003c\/p\u003e\n\n\n\n\u003ch2\u003eWho It Fits and How It Rides\u003c\/h2\u003e\n\n\u003cp\u003eThe bench is fixed rather than on a post, so the fit range is narrower than the frame suggests: about 5 ft 4 in to 6 ft 2 in. Taller riders will feel their knees come up and shorter riders will find the step-in easier than a saddle bike, so sit on one before ordering rather than assuming.\u003c\/p\u003e\n\n\u003cp\u003eOn gravel, packed sand and broken pavement it is stable and the rear coil shock keeps the bench level. On a smooth road the knobby tread hums and the steering is slow, which is the trade for the tire volume that makes the rough surfaces work. The hydraulic discs want a firm two-finger pull rather than a grab, and they stay consistent when the rims are wet or gritty.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eFire roads, farm tracks and packed dirt\u003c\/li\u003e\n\u003cli\u003eBeach towns and campgrounds\u003c\/li\u003e\n\u003cli\u003eStorage where a full-size fat bike will not fit\u003c\/li\u003e\n\u003cli\u003eNot for tight singletrack, stairs or public roads at the top speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\n\u003cdiv class=\"hkm-tablewrap\"\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBike\u003c\/td\u003e\n\u003ctd\u003eAssembled frame, peak 1500W rear hub, 48V 20Ah pack, display\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWheels\u003c\/td\u003e\n\u003ctd\u003eCast alloy 20 x 4.0, fitted at assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePedals\u003c\/td\u003e\n\u003ctd\u003ePlatform pair, left pedal reverse-threaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharger\u003c\/td\u003e\n\u003ctd\u003eCharger with a US plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTools\u003c\/td\u003e\n\u003ctd\u003eHex keys for the stem, seat and pedals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKeys\u003c\/td\u003e\n\u003ctd\u003eTwo battery keys and one NFC card\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRack\u003c\/td\u003e\n\u003ctd\u003eFlat rear rack, frame mounted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFenders\u003c\/td\u003e\n\u003ctd\u003eFront and rear, fitted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLights\u003c\/td\u003e\n\u003ctd\u003eRound grille headlight with turn signals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePaperwork\u003c\/td\u003e\n\u003ctd\u003eAssembly guide and registration card\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery State\u003c\/td\u003e\n\u003ctd\u003eArrives partially charged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003c\/div\u003e\n\n\u003cp class=\"hkm-note\"\u003eBefore the first ride: check the fold joint is fully seated, check both axles, set the fork and shock preload for your weight, bed the disc brakes in with ten firm stops from a walking start, then charge the pack.

That is the listed figure for a 20-inch fat bike on mixed ground, assuming a light throttle hand and flat fire roads. Deep sand, a heavy rider and cold weather pull it down, so treat 40 as the ceiling and 34 as the number to plan around.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hkm-q\"\u003e\n\u003ch3\u003eIs the top speed 25 or 37 mph?\u003c\/h3\u003e\n\u003cp\u003eBoth are printed: 25 mph on the motor poster and 25 to 37 mph on the product page. The 25 mph figure is the one that matches the Class 3 ceiling, and 37 mph is a full-throttle maximum.
