Denago Folding 1 Review: Big Climbing Torque in a Folder for $1,799
Strong torque, a throttle, and a big battery make the Folding 1 a well-rounded daily commuter, as long as you can live with mechanical brakes at this price.
If your days are a mix of side-street commuting and quick errands, and you want a bike you can fold up and stash inside, whether that's a hall closet or the corner of a small apartment, the Denago Folding 1 fits that life well for $1,799. It's a bike, so you get pedal help up to 25 mph plus a that carries you to 20 mph with no pedaling at all. That throttle is the part a lot of buyers are really after, and it's here.
The surprise is how much muscle Denago packed into a folder. The puts out , a big number for a bike this size, so steep hills and loaded starts won't leave you grinding. The catch at this price is the brakes, which are mechanical rather than hydraulic, and that's part of why it lands a 68 out of 100 on our Genius Score, a solid all-rounder rather than a class leader.
Pros & cons
What we like
- is genuinely strong for a folder, so hills and heavy starts feel easy instead of like a workout.
- A lets you ride up to 20 mph without pedaling, which is a welcome break on tired legs or a hot day.
- The 672Wh backs a claimed 57 miles, plenty of cushion for most commutes between charges.
- The folding frame packs down small enough to slide under a desk, into a closet, or beside a couch in a small apartment.
- speed, big torque, and a large battery for $1,799 add up to a fair amount of bike for the money.
Worth weighing
- Mechanical disc brakes are the main trade-off at $1,799, since plenty of rivals now put on bikes at similar money; hydraulics grip harder with less effort at the lever, which counts for more given this bike's 25 mph top speed.
Key specs
The motor & power
The is the strongest part of this bike, and the number that matters most is the . That's a lot of pulling power for a folding commuter.
All that torque means the Folding 1 pulls away from a stop without hesitation and climbs steadily, even loaded with groceries or a full backpack. You shouldn't find yourself standing on the pedals just to hold your speed up a grade.
Denago doesn't publish a output, so judge the motor on that steady 500W and the strong torque figure. Both point to confident, low-effort climbing.
Range & battery
The 672Wh is a healthy size for a bike this small, and Denago claims up to 57 miles on a charge.
That 57-mile figure assumes flat ground and light assist. Real-world range comes in lower once you add hills, a heavier load, or steady throttle use. For a round-trip commute in the 15-to-25-mile range, you'll have room to spare and won't need to plug in every night.
You may see other battery sizes floating around Denago's pages, like a 652.8Wh or a 960Wh pack. Those belong to other Denago models, not the Folding 1. This bike ships with the 672Wh battery, and that's the figure our range read is based on.
Ride & components
The 20-inch wheels wearing 3-inch tires are a smart match for a folder. Small wheels keep the folded package compact, and the fat, cushioned tires smooth out the cracks and curb drops that would rattle you on skinny commuter tires.
The one place Denago clearly trimmed cost is the brakes. Mechanical discs need occasional cable adjustment to stay sharp, and on a bike that can hit 25 mph, a setup would give you stronger stops for less pull at the lever.
Shifting is a Shimano 7-speed, the standard setup on folders like this. Seven gears cover a normal commute without any fuss, and as with any bike, you'll spin out of useful gears once you get near the 25 mph top speed.
The complete bike weighs 62 pounds, normal for a fat-tired folder, and the fold lets you lift or roll it into a car instead of wrestling a full-size frame.
Price & value
At $1,799 the Folding 1 sits squarely in the middle of the commuter market, and you get a fair amount for it.
The strong torque, the large battery, and the speed are where the value is. What keeps it from being a standout deal is where Denago saved money: the mechanical brakes sit a step below what a few rivals put on bikes at similar money.
So the honest read is a well-rounded folder that climbs well, cruises fast, and gives you a throttle, priced sensibly for what it is.
Who it's for
The trunk-and-transit commuter
If your commute means hauling the bike aboard a train or bus or squeezing it through a cramped hallway at home, the folding frame is the whole point here. You get a full-power bike that packs down small, and the means you can roll away from a stop or up a short rise without breaking a sweat before work.
The rider with hills on the route
If your everyday ride includes climbs that make lighter e-bikes struggle, the of pulling power is a real advantage. It hauls you and a loaded pannier up grades steadily, so a hilly neighborhood or a bridge on the commute won't be the thing that decides your bike.
The hard-braker on steep descents
If you regularly drop down long, steep hills or ride stop-and-go traffic where you're on the brakes constantly, think hard about the mechanical discs. They handle everyday stops fine, but on a sustained descent brakes hold their power better and don't tire out your hands the way cable-pulled ones can.
The pedal-only fitness rider
If you want the bike mainly for exercise and plan to pedal every mile, the throttle and 25 mph top speed are more capability than you'll actually use. A simpler bike tuned for a steady workout may suit you better and cost less.
