Choose the Zumi S011 if you want a compact folding fat-tire e-bike for errands, commutes and easy storage, or the Zumi EX-01 if you want a dual-battery electric dirt bike for off-road riding on trails and private property.
Zumi is one of the newest brands at Watt Wheelz, and the two Zumi models you can currently order sit at opposite ends of the range: a light folding e-bike and a full-suspension off-road dirt bike. This guide compares them using the Zumi collection. These are specification-based recommendations, not a controlled test and not firsthand test results. We checked the figures below against the specification information Zumi supplied to Watt Wheelz and our own product records on November 3, 2026.
We have deliberately left prices out of this guide. Prices can change during the holiday sales, so the live price on each product page is the only number you should trust.

Range depends on rider weight, speed, terrain, temperature and riding style. The EX-01's 96-mile figure is Zumi's maximum with both batteries, so treat it as a best case rather than a daily expectation.
How We Chose and Compared These Models
Zumi's public website does not currently list the S011 or the EX-01, so we used the specification information Zumi supplied to Watt Wheelz and cross-checked it against our product records. We compared motor, battery, top speed, range, maximum load, weight, frame, tires, suspension and brakes, and we did not add any figure that Zumi has not published. Because these two models are built for very different riding, the comparison is mainly about matching the right type of vehicle to where and how you will ride.
Zumi S011: Best Folding E-Bike for Storage and Errands
The Zumi S011 pairs a 36V 350W motor with a 36V 10Ah battery in a folding aluminum alloy frame. Zumi lists a top speed of up to 16 mph, a range of about 19 to 25 miles (30 to 40 km), a maximum load of about 396 lb (180 kg) and a net weight of 53.9 lb (24.45 kg).
Its 20 x 3.0 inch fat tires and front suspension add grip and cushioning on rough pavement, a 7-speed drivetrain helps on gentle hills, and mechanical disc brakes handle stopping. Unfolded, the bike measures 1560 x 280 x 1190 mm, and Zumi lists a packing size of 1400 x 310 x 590 mm.
The S011 suits apartment dwellers, RV and boat owners, and anyone who needs to fit an e-bike in a car trunk or a small storage space. At 53.9 lb, it is still worth trying a lift before you plan on carrying it up stairs every day. Its modest motor and battery make it best for shorter, relaxed rides rather than long commutes or steep climbs. It is available in black and white; check the product page for current stock. Compare it with other folding e-bikes if storage is your priority.
Zumi EX-01: Best for Off-Road Trail Riding
The Zumi EX-01 is an off-road electric dirt bike with a 52V 1500W motor and two 52V 15Ah batteries. Zumi lists a top speed of 28 to 37 mph (45 to 60 km/h) for off-road use only, a range of about 42 to 96 miles (68 to 155 km) with both batteries, a maximum load of about 396 lb (180 kg) and a net weight of 120.4 lb (54.6 kg).
It uses a high-strength steel frame, front and rear suspension, hydraulic disc brakes, a 19-inch front and 17-inch rear wheel setup and an LCD display, and Zumi lists a 52V 2A charger. The dual batteries are the main reason for its long range figure.
The EX-01 suits riders with access to trails or private land who want a motocross-style electric dirt bike. It is not a street bike: ride only where this type of vehicle is permitted, and wear a helmet and full protective gear. It is currently offered in black. Our electric dirt bike buying guide covers sizing, safety and where you can ride.
Which Zumi Is Best for Your Use?
Best for small spaces and car trunks
The S011. It folds and weighs 53.9 lb, according to Zumi.
Best for errands and short commutes
The S011, with a top speed of up to 16 mph and about 19 to 25 miles of range.
Best for trails and private land
The EX-01, with front and rear suspension, hydraulic disc brakes and dual batteries. It is for off-road use only.
Best for long rides
The EX-01, with Zumi's range figure of about 42 to 96 miles. For pavement riding, the S011's shorter range is better suited to local trips.
Certification, Shipping and Warranty: What to Confirm
We did not find a UL certification statement for either model in the information we checked, so we have not claimed one. If a certification matters for your building, insurer or local rules, confirm it with us before you order. Zumi has not assigned an e-bike class to the S011 in the information we checked, and the EX-01 is for off-road use only, so check your local rules on where each may be ridden.
Warranty terms are set by the brand, so ask us which warranty and return terms apply to an order placed through Watt Wheelz, and ask us to confirm shipping availability for your address. For help with fit or setup, contact Watt Wheelz.
