Yozma IN10

The listing title calls the IN10 an "Electric Dirt Bike", an "Off Road Electric Motorcycle" and an "Ebike" in the same line, and the bullets go on to call it an "electric bike". Only the first two are accurate. The listing photo and Yozma's studio photos show foot pegs and no pedal cranks, and the motor is a throttle-driven mid-drive. Yozma is clearer than the listing: its own product page lists the road rating as "Off-Road Only" and asks buyers to confirm they are 14 or older, adding that the vehicle "is intended for off-road use only and is not permitted on public roads". Amazon files it under Motorcycles & ATVs, and it was #1 in Amazon's Motorcycles & ATVs (Vehicles) category on October 28, 2026. That is the correct shelf, which is more than we can say for the ASKGO Dirt 5500, sold under Electric Road Bikes.

The federal definition of a low-speed electric bicycle in 15 U.S.C. § 2085 needs three things at once: fully operable pedals, a motor under 750 W, and a motor-only top speed under 20 mph. The IN10 misses all three. It has pegs, its rated motor is 1,200 W by Yozma's own figure, and its top mode is 40 mph. Even its slowest mode, which Electrek reports caps at 18 mph, does not help, because the pedals are still missing. California spells the category out directly: Vehicle Code § 436.1 defines an off-highway electric motorcycle as one "not equipped with pedals from the manufacturer". Our guide to whether Sur-Rons are street legal covers this class of machine state by state, and the answer for the IN10 is the same.

In practice that means private land, motocross tracks and designated off-highway vehicle areas, with whatever registration or trail permit your state requires for an off-road motorcycle. The listing itself tells buyers to "check the local legal age or license requirements" and says teens should ride "only under adult supervision". Take both seriously: youth age limits for off-highway vehicles are set state by state and are separate from e-bike age rules.

Most dirt-style listings on Amazon quote a peak wattage and nothing else. The IN10 listing does the same (2,600 W peak), but Yozma's own spec post on yozmasport.com goes further: "2600W peak mid-drive motor (1200W rated), powered by a 48 V brushless system". Rated output is the figure statutes and comparisons should use, so that is the number in our spec table, with the peak alongside it. Yozma's European press release adds 146 N.m of torque and Electrek's spec sheet repeats it.

A mid-drive layout puts the motor's mass low and central, between the pegs, rather than in the rear hub, and drives the rear wheel through a chain. Our mid-drive vs hub motor guide explains why that tends to help handling. The listing claims the IN10 climbs slopes up to 30 degrees. Electrek reported that the claim held with a lighter rider of about 140 lb, and that with the reviewer's own 200 lb aboard the motor was working hard on steep grades. Electrek also said the 40 mph top mode needs a long runway and that the bike usually plateaus around 35 mph. Ride Review, riding at 220 lb, reported reaching 38 mph. One small disagreement: Yozma's product page gives the top speed as "28-40 Mph" across its three modes, while Electrek reports the modes capping at 18, 24 and 40 mph.

The listing states a removable 48 V x 23 Ah battery, which is 1,104 Wh. Yozma, Electrek and CleanTechnica all give 23.4 Ah, which is 1,123 Wh. The gap is under 2%, and we carry the listing's lower figure.

The listing claims "up to 53 miles". Divide it: 1,104 Wh / 53 miles = 20.8 Wh per mile. That is a plausible figure for a light e-bike ridden gently. It is not a plausible figure for a 121 lb machine on knobby tires with a rider aboard, climbing and accelerating off-road, where 30 to 45 Wh per mile is a more honest expectation. Yozma's own spec post is more careful than the listing and gives a range of 35 to 53 miles depending on rider weight, terrain and temperature.

The two riding reviews land near the bottom of that band. Electrek called 35 miles of spirited trail riding "totally believable", which is about 31.5 Wh per mile. Ride Review estimated 20 to 25 miles riding hard and 30 to 35 miles mixed. We plan on 30 miles of mixed off-road riding (about 37 Wh per mile), and less if you live in the 40 mph mode. Charging is slow: the included 5 A charger takes about 6 hours from empty, per Electrek, and both Electrek and Ride Review named it as the weak point.

This is where the IN10 earns its price. The listing states a 220 mm travel hydraulic front fork and a nitrogen-charged rear shock, and Electrek describes both ends as adjustable. Braking is hydraulic disc front and rear, which Electrek lists as 190 mm rotors, paired with EABS regenerative braking. Electrek wrote that the brakes "haul this thing down fast and confidently". The one suspension criticism was that the reviewer bottomed it out a few times on rougher ground, which is the expected limit of a short-travel mini bike under an adult.

Fit is the decision most buyers will get wrong. Yozma's spec post gives a rider height of 120 to 175 cm (3 ft 11 in to 5 ft 9 in), a 28-inch seat height and a 265 lb maximum load. Its product page writes the height range as "3.94ft - 5.9ft", which read as decimal feet would stretch to nearly 5 ft 11 in, but 175 cm is 5 ft 9 in, so plan on the lower figure. Ride Review warned that riders 5 ft 10 in and taller may feel cramped. The listing says "Teens & Adults", and that is true for smaller adults only. Yozma also states an IPX6 water rating, a high-carbon steel frame, a 41.7-inch wheelbase and 9 inches of ground clearance.

Neither the Amazon listing nor Yozma's spec post names UL 2849 (the e-bike electrical system standard) or UL 2271 (the battery pack standard), and neither names a test laboratory. The listing's "Ultimate Battery Safety" bullet describes a battery management system, nothing more. Ride Review states that "all electrical components are UL certified" but does not name a standard or a lab, and Yozma's European press release says the IN10 is CE certified, which is a European conformity mark rather than a US safety listing. Until Yozma names the standard, treat the IN10 as having no stated UL certification. Yozma's product page states a 12-month warranty period. With a battery over 1,000 Wh, charge it on a hard floor, away from exits, and never unattended overnight; our battery fire safety guide covers the rest.

Three outside sources cover this exact model, and they are not equal. Electrek (Seth Weintraub, April 18, 2026) is a riding review with specific observations, and it does not say how the bike was obtained. Ride Review (November 27, 2025) is also a riding review, and it states that Yozma sent the bike free of charge and that the page carries affiliate links. CleanTechnica (September 11, 2025) is a spec overview with no riding, and its figures match Yozma's own blog post. Owner reports beyond these were not available to us, and Ride Review mentions occasional quality-control issues without detail.

Buy it if you are buying for a teen or a rider under about 5 ft 9 in, you have private land, a track or OHV trails to ride on, and you want hydraulic brakes and real suspension rather than a toy. Yozma's own store sells the same black bike, and its sale price there in September 2026 sat slightly above Amazon's $1,049 (as of Oct 30, 8:11 AM EDT, subject to change) at our October check. Ignore the much higher "regular price" Yozma prints beside it: no review we read found the bike selling at that figure.

Skip it if you are over 5 ft 10 in or near the 265 lb limit, if you need a road or bike-path vehicle, or if a named UL standard is a requirement for charging indoors. If street use is the point, start with our street-legal electric dirt bike picks, which only include bikes that fit the three-class system, and check your state on the street-legal-by-state page.
