Electrifying a 24-inch front wheel for the least money possible is a narrow want, and this kit is aimed straight at it.
The HCYHSLH 24-inch front hub kit sits in the cheapest fifth of the 191 conversion kits we track, and it sold for about 108 when I checked, which undercuts nearly everything else in the band. The price is real. So is the catch sitting next to it.
The record here is three confirmed-purchase texts, every one of them written inside a three-week stretch, and they split the way a histogram with no middle band splits: three buyers pleased, one motor dead at three months. Nobody has owned this wheel through a season. The 3.8 average is four ratings, two of which carry two words or fewer between them.
What follows works the listing from the box outward: what actually ships, the contradiction hiding in the title, the fitment claim that overreaches by a foot, the arithmetic the slope claim skips, and what the record can and cannot tell you before you order.
What the kit ships, and what it never claims
The parts list is the strongest thing about this listing, which on this tier of kits is rare enough to lead with.
The spec table's Included Components row reads complete: the 24-inch front wheel with the brushless hub motor, an electric controller, two hand brakes, two handle grips, two junction boxes, a spoke key, a controller bag, a thumb throttle, a strip, and a winding item the row cuts off mid-word. Brakes and grips shipping in the carton is not a given at this price. Neither is the controller bag.
Read the same row for what never appears. No battery. No charger.
No pedal-assist sensor anywhere in the list. This is a throttle-only kit, and the title agrees, selling a thumb throttle and nothing else on the control side. That distinction matters more than it looks: a throttle-only 750W machine sits right at the boundary of how United States rules define a low-speed electric bicycle, and jurisdictions treat throttle-only machines differently from pedal-assist ones. Buyers in strict states should check before the wheel arrives.
The warranty row reads one-year, which is a real promise in writing, on a listing where many siblings print nothing. Whether the promise behaves like one is exactly what the record cannot say, and I will come back to that. Compare it against the rest of the field in our conversion kit comparison table.
The title argues with its own motor
The title calls it a brushless toothed hub motor. A later bullet says the drive system has no moving chains or gears. Both statements are trying to be true, and the difference between them is the most mechanically useful thing on the page if you read it correctly.
Toothed means geared. Hub motors come in two builds: direct-drive, where the rotor is the wheel, and planetary-geared, where a smaller motor spins fast through internal reduction gears to make torque at the wheel.
A geared hub is the lighter build, and the internal gears are exactly the kind of part that can make noise. The bullet's phrase is about there being no chain drive, which is true of every hub motor, but the title's own word tells you there are gears inside this one. On a listing this thin, that one adjective is the tell.
The record agrees with the tell. The one-star text, the only mechanical report in the file, says a bad sound came from the wheel from the day it was installed, and that the motor quit working altogether at three months. A geared hub's noise signature at install, followed by an early death, is a coherent story.
The same owner left the advice worth the whole article: if this motor makes any noise from the wheel that does not sound right, put it back in the box and send it back. On a geared hub, install-day noise is not character. It is a symptom with a return window attached.
One more title detail: the speed figure is printed 390PRM. RPM misspelled in the title itself tells you how much editing this page got, and it is the same care level the fitment bullet shows next.
The application bullet says this kit suits 24-inch bicycle racks and aluminum wheels of 12, 16, 18, 20, 24, 26, 700c and 28 inches, on two-wheeled, mountain and folding bikes.
One fixed 24-inch front wheel, eight claimed fitments. A 24-inch motor wheel cannot be laced into a 12-inch rim, and a 28-inch bike needs a wheel that reaches its brake tracks, not one three sizes down. This is template copy, the same bullet reshuffled across a catalog of differently-sized kits, and the 24 in the middle is the only true part.
The real constraints are in the spec table and the title. Wheel size 24 inches, rim size 24 inches, brake style disc or V-type, which covers the two common fork fittings. Measure your fork spacing and your brake mount before ordering, and ignore every wheel size in the application bullet except the one in the title.
The arithmetic the slope claim skips
Bullet three gives us two numbers: 35N.m of torque and a claim to climb up 12-degree slopes. Put both on the same wheel and they argue.
A 24-inch wheel has a radius of about 0.30 meters, so 35N.m at the hub is about 115 newtons of force at the ground. Holding a 12-degree grade takes, for a 120-kilogram bike and rider, roughly 245 newtons before rolling resistance adds its share.
The listing's own torque figure delivers about half of what its own slope claim needs. The 12-degree line assumes a lighter rider, a gentler reading of slope, or no physics check at all. Plan on real climbs being slower and steeper cuts being walked, or buy more motor.
The speed figure survives the check better. 390rpm on a typical 24-inch tire, about 1.92 meters per turn, works out to about 45km/h or 28mph. That is a no-load ceiling, not a riding speed, and a real rider on a hill will see less, but the number is at least arithmetically honest for the wheel size it names.
Current draw at 750W on 36V is about 21 amps, and no controller rating is printed, so that is the figure to ask the seller about if you plan to run bigger batteries. One last conversion: the 220.46 lb load rating is 100kg wearing two decimal places, and it is the load limit, not the 19.84 lb the wheel itself weighs.
Three texts inside three weeks, no middle band
The rating count is 4, the average is 3.8, and the histogram reads 71 percent five-star, 29 percent one-star, nothing between. Three of the four ratings have text, and all three are confirmed purchases written between September 10 and October 2, 2026.
The five-star texts carry almost nothing. One is the words works great and nothing else.
The useful positive is the October text from a buyer who had to replace a wheel on an existing e-bike, found this one compatible, and says they have a few more bikes to do and will be purchasing a few more. That is the only fitment evidence in the file, and it is secondhand comfort at best: one 24-inch wheel fit one 24-inch bike.
The one-star is the text that does the work. The motor made a bad sound from install, lasted three months, and quit altogether, and the owner's advice is to treat install-day noise as grounds for an immediate return.
The text never says whether a warranty claim was made. That silence is the gap: the listing promises a year, the failure arrived at three months, inside the promise, and the record does not show anyone testing the promise. What nobody has reported anywhere in the file: top speed under load, range on any battery, rain behavior, install time on a disc fork, or a warranty experience.
Cheapest fifth of the table, youngest record
On price this kit sits in the cheapest fifth of everything we track, and a parts list this complete is rare anywhere near this price. Compare it against the rest of the field in our conversion kit comparison table.
Buy it as a cheap first conversion only if you understand what the safety net is.
The one-year warranty row is a promise nobody in the record has tested. The return window is protection with evidence behind it, and the one owner whose motor died says the first weeks decide everything: a wheel that spins silent at install is the one that lasts in this file, and the one that rattled is the one that died.
Order the kit on Amazon from a seller with returns you can actually use, ride the first hundred miles with your ears on, and treat any new sound from the hub as a deadline.
FAQ: the charger you supply, the 35N.m hill math and the 26-inch fitment the bullet gets wrong
Does the kit include a battery or charger?
No. The Included Components row lists the wheel, controller, hand brakes, grips, junction boxes, spoke key, controller bag, thumb throttle and winding set, and nothing that stores or delivers charge. You supply a 36V battery and charger separately.
How fast will it go?
The title's 390rpm works out to about 45km/h or 28mph as a no-load ceiling on a typical 24-inch tire. Real riding speed sits under that, and no buyer has reported a measured figure.
Will it climb hills?
Not the way the bullet says. 35N.m on a 24-inch wheel is about 115 newtons at the ground, and a 120kg bike and rider needs about 245 newtons just to hold a 12-degree grade. Expect gentle hills and walk the steep ones.
Is it suitable for my 26-inch bike?
The fitment bullet claims eight wheel sizes from 12 to 28 inches, which is template copy. The wheel that ships is 24 inches. If your bike takes a 26-inch wheel, this is the wrong wheel, whatever the bullet says.
What does the record actually support?
Three badged texts inside three weeks: one two-word positive, one replacement install that fit, and one motor that made noise from day one and died at three months. Nobody has reported speed, range, rain, or a warranty claim. If it isn't the right fit, the conversion kit comparison table sorts every option we track.
