Tomofree S1 PRO Folding Electric Bike Review 2026: Worth $420?
The Tomofree S1 PRO folding electric bike offers 800W power and 40-mile range for $420, but a 76 lb weight, 180 lb total load limit, and single 1-star review make it a high-risk buy.

How this e-bike scores for different riding styles
This bike excels at portability with its 14-inch folding design and relatively compact dimensions (50x22x42 inches). At 76 lbs it's heavier than some folders, but the small wheel size and folding capability make it excellent for tight storage and multi-modal transport.
The 40-mile range and 20 mph speed work well for most commutes, plus the folding design makes it easy to store at work or take on public transit. However, the lack of integrated lights and fenders reduces practicality for year-round commuting.
The two-seater design and 40-mile range make it fun for casual rides with a passenger. The 20 mph speed is comfortable for leisurely cruising, though the small wheels and basic suspension limit comfort on longer recreational rides.
The 800W motor provides decent power, but the 20 mph speed is limited by regulations rather than capability. The power-to-weight ratio of 10.5 W/lb is moderate, and the compact design prioritizes portability over performance thrills.
The 180 lb max load capacity and rear rack provide some cargo capability, but this is significantly below average for utility e-bikes. The compact frame and small wheels aren't designed for heavy hauling or serious cargo work.
The small 14-inch wheels and high carbon steel frame aren't designed for serious trail riding. While it has rear suspension, the compact design and street-oriented build make it unsuitable for challenging off-road terrain.
Our Verdict
The Tomofree S1 PRO is a budget folding electric bike priced at $420 that targets riders who need compact storage and affordable short-distance commuting. The 800W motor delivers enough watt output to handle moderate inclines, and the 48V 20Ah battery (960Wh) provides a 40-mile range on pedal assist before needing a full charge. Three pedal assist levels let riders manage torque output based on terrain, though the motor torque is modest compared to mid-range 750W hub motors in the $700–$900 bracket.
The 14-inch folding frame stores in car trunks and apartment closets, and the two-seater design is rare at this price point. The value calculation works on paper — a 40-mile range and 800W motor at $420 puts cost per mile well below most similarly-priced e-bikes.
The Tomofree S1 PRO carries a 180-pound total load capacity covering rider plus cargo, which eliminates most riders over 150 pounds once gear is factored in. At 76 pounds, the bike is too heavy for most people to carry upstairs, undermining the folding benefit. There is no integrated display, no lights, and no UL or CE safety certification. The single verified review is 1 star, signaling reliability problems beyond normal budget trade-offs. Riders who need dependable daily transportation or weigh more than 150 pounds should budget $600–$800 for a certified alternative with a proven track record.
What We Like
- Priced at $420 with an 800W motor and 40-mile range, the Tomofree S1 PRO offers a lower cost per mile than most sub-$500 e-bikes
- 48V 20Ah battery (960Wh) delivers a genuine 40-mile pedal assist range on a single charge, above average for this price tier
- 14-inch folding frame collapses to 50 x 22 x 22 inches, fitting in most car trunks and closets with minimal disassembly
- Two-seater frame accommodates a rider plus a small passenger, a feature absent from most compact electric bikes under $600
- 3-speed pedal assist lets riders reduce watt draw on flat terrain to extend range, or apply more torque on inclines up to the 800W motor ceiling
What Could Be Better
- 180 lb total load capacity covers rider and cargo combined, making the Tomofree S1 PRO unsuitable for anyone over 150 lbs once gear is factored in
- Weighs 76 lbs — 15–25 lbs heavier than the folding electric bike category average — making it impractical to carry upstairs or lift onto transit racks
- No integrated lights, display, or speedometer included, requiring additional purchases for safe night riding and basic ride data
- Single verified review is rated 1 star, suggesting quality or reliability problems that go beyond typical budget e-bike trade-offs
- 14-inch wheels amplify road vibration and reduce stability at the 20 mph top speed, with no front suspension to absorb impact

Frequently Asked Questions
Common questions aboutTomofree S1 PRO Folding Electric Bike for Adults, 800W Motor, 20MPH Speed, 48V Removeable Battery, 40Miles Range,14inch Compact Foldable Electric Bike, Mini E Bikes for Adults and Teens
How far can this bike go on one charge?
The bike can travel 40 miles on a single charge with its 48V 20Ah battery. This is the maximum range, so your actual distance might be less if you ride fast, go uphill a lot, or carry a passenger.
How much weight can this bike carry?
The maximum load capacity is 180 pounds total. This includes the rider and anything you're carrying like bags or a passenger. If you weigh more than 150 pounds, you won't have much room for extra weight.
Is this bike easy to fold and store?
Yes, it has a folding design with 14-inch wheels that makes it very compact. When folded, it's easier to store in small apartments or car trunks, but at 76 pounds it's still quite heavy to lift and carry around.
How fast does this electric bike go?
The top speed is 20 miles per hour. This is a standard speed limit for electric bikes in most places, so you can ride it legally on bike paths and roads without special licensing.
Does it come with lights and a display screen?
No, this bike doesn't have built-in lights or an LCD display screen. You'll need to buy and attach your own lights if you want to ride safely at night, and you won't have a screen showing your speed or battery level.
