Electric dirt bikes are growing faster than any other segment in the powertrain market, with projections pointing to double-digit annual growth through at least 2033. Two U.S.-based brands, WocoMotors and Yozma (YozmaSport), are competing for the attention of riders who want powerful, zero-emission off-road machines at accessible prices. This comparison covers the dimensions that matter most: performance specs, pricing, parts availability, support, and overall value.

Performance and Specs
WocoMotors ROCRUN Lineup
The ROCRUN R1 is built for adult riders and runs a 60V mid-drive motor paired with a 60V 27Ah battery pack. It tops out at roughly 43 mph with a max range of about 31 miles. The R2, marketed toward younger riders, actually packs more punch: a 60V 27Ah battery, an 80A discharge controller, and a top speed around 50 mph with up to 37 miles of range. Both bikes use motorcycle-proportioned wheels (the R2 runs 17" front and 14" rear), giving them a planted, full-size feel on the trail.
Yozma's IN 10 and IN 10 Pro
Yozma deserves credit for building a strong entry-level option. The IN 10 uses a 2,600W mid-drive motor, a 48V/23.4Ah removable battery, and a three-speed mode system (18, 29, and 40 mph) that lets parents cap speed for less experienced riders. That speed-limiting feature is genuinely useful for families. Yozma claims up to 53 miles of range under ideal conditions, though real-world riding tends to land closer to 35 miles. An Electrek review from April 2026 noted the motor plateaus around 35 mph in practice despite the 40 mph spec.
The IN 10 Pro steps up to a 5,500W peak mid-drive motor, a 60V/27Ah battery, and a claimed top speed of 50 mph. On paper, Yozma lists up to 60 miles of range, but an independent RiderGuide test measured roughly 22 miles of hard off-road riding in Mode 2 with some Mode 3 use. That gap between claimed and real-world range is worth noting for anyone planning longer trail sessions.
How They Compare
The ROCRUN R2 and the IN 10 Pro share similar battery capacity (27Ah) and identical wheel sizing (17"/14"). The R2 matches the IN 10 Pro's 50 mph top speed while running a higher-voltage 60V platform, which generally translates to more consistent power delivery under load. For adult riders, the R1 offers a solid mid-range option, while the R2 punches into performance territory that competes directly with Yozma's flagship.
Pricing and Value
Yozma's pricing is transparent and competitive: the IN 10 starts at roughly $1,099, and the IN 10 Pro sits between $1,799 and $2,000 depending on the retailer. These are fair prices for the specs on offer, and the IN 10 in particular hits a sweet spot for budget-conscious first-time buyers.
WocoMotors operates as a factory-direct brand, which means we cut out the layers of middlemen that inflate retail prices. Our price-match guarantee backs that up. If you find a comparable spec at a lower price, we will match it. That direct-to-consumer model also means we control quality at the source, from the factory floor in China to our warehouse in Fontana, California.
Parts, Accessories, and Long-Term Ownership
This is where WocoMotors pulls ahead in a way that matters more than most buyers realize at the point of purchase. Owning an electric dirt bike is a long game. Batteries degrade, controllers fail, brake pads wear out, and tires need replacing. WocoMotors stocks a comprehensive spare parts catalog that covers not only our own ROCRUN models but also parts compatible with Minimotors and Voromotors scooters and bikes. Batteries, motors, controllers, tires, brakes, chargers, lights: we carry them all, and we offer next-day delivery on parts orders.
Yozma's parts availability, by contrast, is limited to their own models. That is not unusual for a newer brand, but it does mean riders may face longer waits or fewer options when something needs replacing. For anyone who plans to ride hard and ride often, easy access to replacement components is a real advantage.
Shipping and Support
WocoMotors ships standard orders in 7 to 10 days, with an optional next-day domestic shipping upgrade. Yozma's estimated delivery window is 10 to 14 business days. Both brands offer warranty coverage, though the details differ. Yozma provides a 1-year manufacturer warranty on the frame, battery, and original components, with labor and installation costs falling on the owner. WocoMotors backs its products with a warranty policy and dedicated customer support, including downloadable user manuals for every model.
We also run an affiliate program and a rider reviewer program designed to build a real community around the brand. Honest feedback from actual riders shapes how we develop future products and keeps us accountable.
Availability
One area where we want to be upfront: as of mid-2026, both the ROCRUN R1 and R2 are listed as backordered on our website. Demand has outpaced supply, and we are working to restock as quickly as possible. Yozma's models appear to be in stock, and the IN 10 has accumulated over 1,164 reviews on its product page, which reflects strong consumer traction. The ROCRUN R1 has 93 reviews and a growing customer base. We are a younger brand (founded in 2023), and we are scaling fast.
Who Should Choose Which?
Choose Yozma If:
You want a proven entry-level electric dirt bike right now. The IN 10 at around $1,099 is a solid first bike, especially for younger or less experienced riders who benefit from the three-speed mode system. Yozma has built real momentum and a sizable review base that speaks to customer satisfaction.
Choose WocoMotors If:
You care about long-term ownership costs, parts availability, and factory-direct pricing. The ROCRUN R2 competes head-to-head with the IN 10 Pro on specs while running a higher-voltage platform. Our spare parts catalog is unmatched in this segment, covering our own models and major third-party brands. Faster standard shipping, a price-match guarantee, and a growing rider community round out the package. If you are willing to wait for restock, WocoMotors offers a more complete ownership ecosystem.
The Bottom Line
Yozma has earned its place in the electric dirt bike conversation, particularly at the entry level. But WocoMotors is building something broader: a factory-direct brand with competitive performance specs, an extensive parts infrastructure, and a commitment to keeping riders on the trail for years, not just months. The electric dirt bike market is projected to nearly double in the U.S. by 2033, and we intend to be the brand that riders trust for the long haul.
