Denago Folding Model 1 E-Bike Review, 2024
It’s fast! It folds! It flies uphill! Denago delivers another fun and functional e-bike with the Folding Model 1.
Things got off to a great start in our testing thanks to the Folding Model 1’s power and speed. The bike’s 500W rear hub motor and quick acceleration did not disappoint; as a Class 2 and 3 e-bike with a throttle, it effortlessly carried us to its maximum speed of 25 miles per hour. We expected nothing less from Denago!
All of that power helped the Folding Model 1 to conquer hills in record time (with a caveat or two). We’ll go over those details in our Hill Test section below!
Of course, power doesn’t mean much on a folding bike if it doesn’t actually fold well; the Folding Model 1 has an effective quick-release clamp that holds its two halves together firmly but also allows the bike to collapse in no time.

- A speedy bike with good acceleration! As a Class 3 e-bike with a 500W motor, the Folding 1 can zoom effortlessly up to 25 mph.
- Able to tackle hills with ease! For us, the bike demonstrated great hill climbing even in PAS 2.
- Super quick folding! The mechanism on the Folding 1 is one of the fastest we’ve seen. Denago advertises just 30 seconds from start to finish.
- Accommodates riders between 5’-1” and 6’-5” despite having just a single frame size!
- Includes a functional accessory package! With lights, fenders, and a rear cargo rack with a bamboo deck, the Folding 1 comes well-equipped.
- We love the Denago 1’s ability to go fast and climb hills, but we’d prefer to see a more sensitive cadence sensor for quicker motor re-engagement.
- The Folding 1’s extended plastic stem helps the bike to fit tall riders, but we’d like to see a less flexible component for crisper handling.

Denago Folding 1 Review: E-Bike Overview
The Folding Model 1 doesn’t break the pattern here – at least not too much. The bike’s 500W rear hub motor might seem small on paper, but it packs a punch! Initially, its power builds comfortably but confidently, and allows the Folding Model 1 to cruise steadily at its top speed of 25 miles per hour. If you’re already moving and you bump up the bike’s pedal assist system (PAS) setting, though – hold on! Riders who like thrills will undoubtedly appreciate this kick.
In our experience, it’s uncommon for an e-bike to have enough power in its low PAS settings to climb hills confidently. Even huge fat tire bikes with 750W (or higher) motors often need to be in their mid-to-high settings to do the job quickly and effectively. The Denago Folding Model 1 surprised us with its ability to power up hills in PAS 2 with only minimal effort from the rider!
As with most folding e-bikes, the Folding Model 1 collapses in two main locations: at the midpoint of its frame and the base of its stem. The main frame hinge is one of the fastest and easiest we’ve seen to collapse; Denago’s advertisements claim that the bike can be fully folded in 30 seconds, and we found (with some practice) that that time could be cut down even shorter! The bike also has a quick-release seatpost clamp and folding pedals, which can reduce its total size to roughly 20” W x 35” L x 30” H. This allows the bike to be stashed beneath a desk or table, or transported in the trunk of a car for more freedom to roam!
For those who are curious, we have a separate article explaining our testing methods and philosophy. To read more about how this specific bike performed in our Hill Test, as well as in our Range, Circuit, and Brake Tests, read on to see our full Denago Folding Model 1 review!
Denago Folding 1 Review: Circuit Speed Test
Our Circuit Test, explained above, is a series of timed laps that allowed us to get a feel for the Denago Folding Model 1. In particular, we sought to gain a greater understanding of the bike’s Shengyi 500W rear hub motor, its cadence sensor, its handling, and its pedal assist system.
In our first loop with no motor assistance, we appreciated that the bike pedaled fairly smoothly and easily. According to Denago, the Folding Model 1 weighs 62 lbs, which is somewhat on the heavy side for a folding bike. This became more apparent on the short incline in our test circuit, but otherwise, as long as we pedaled in low gears, the bike moved well on leg-power alone.
Once we engaged the bike’s PAS, its motor kicked in to offer pedal assistance. I typically think of an e-bike’s PAS 1 setting as effectively serving to remove the weight of the bike, but I’m not sure this was true with the Folding Model 1; I would personally like to see this setting have a little more “oomph.” But as I referenced earlier, the bike performed surprisingly well on our test circuit’s small hill even in PAS 2, and its feel on flat ground was greatly improved. As we moved up through its PAS settings, the motor yielded steady – and fun – increases in power that were reflected in our data (as seen in the graphic above). Generally speaking, we really like to see this pattern!
On the other hand, this test highlighted one feature of the Folding Model 1 that we think could use improvement: its cadence sensor. I mentioned previously that the bike’s initial motor engagement is good, but we noticed that it lacked responsiveness when re-engaging after braking or coasting. We explain some of the nuances or typical behaviors of e-bikes with cadence sensors in our article explaining throttle vs pedal-assist, but the two or more full pedal rotations that we encountered with the Folding Model 1 were unusual. This experience was far less off-putting than on a heavier e-bike that would expectedly be more difficult to pedal with just leg power, but regardless, we’d prefer to see a more sensitive sensor with more rapid re-engagement in the future.
As a Class 2 and 3 e-bike, the Folding Model 1 includes a throttle to carry its rider up to 20 miles per hour. In contrast to many (and perhaps most) of the e-bikes we at Electric Bike Report have tested, the Folding Model 1’s throttle does not function when at a complete stop, and requires the bike to be moving at roughly 2 mph before it will engage.
We initially weren’t the biggest fans of this element of the bike (and if I’m being honest, more responsive “throttle on demand” power is more fun), but after reaching out to Denago, we came around to their logic. After asking why they chose the included throttle, our contact advised us that this was a safety feature. The Folding Model 1’s current throttle setup prevents it from accidentally taking off on a user if they forget to turn the bike off before folding it up for storage. We love it when brands consider rider safety a top priority, and so we have to acknowledge Denago’s efforts here!
Denago Folding 1 Review: Range Test & Battery Performance
To evaluate the Denago Folding 1’s range capabilities and motor/battery efficiency we performed a real-world range test. Our methods are explained above, but after performing our Circuit Test, we felt that the best settings for this trial were PAS 2 and PAS 5.
The Folding Model 1 is an unusual case for a couple of reasons. First, Denago does not currently advertise an estimated range for the bike – at least not in an obvious location. Again, we reached out to the company with questions, and our contact suggested that most riders should achieve at least 40 miles.
Second, the actual range that we measured was unusual. With the bike’s 500W rear hub motor and 48V, 672 watt-hour (Wh) battery, the Folding 1 traveled nearly 42 miles in its maximum PAS setting, and nearly 50 in PAS 2.
It’s relatively uncommon for an e-bike to have such similar results; a difference of between 15 or 20 miles is more typical. However, we were pleased to see that the Folding Model 1 both met and exceeded Denago’s estimate even in PAS 5. The figures we arrived at in our testing are completely respectable given the bike’s motor wattage and battery watt-hour ratings. We discuss more about that relationship in our guide to e-bike batteries.
I noticed during my rides that, especially in the bike’s max-assist setting, I found myself often reaching for the shifter to access an additional gear that wasn’t there. This isn’t uncommon when it comes to Class 3 e-bikes, but the Folding Model 1 can feel “ghost-pedaley” in PAS 5 despite the 48-tooth chainring and gearing range of 12-32T on its cassette. Personally, I wouldn’t be opposed to an additional 8th gear, but as it is, the bike’s current configuration allows its rider to relax and rely on the motor in its highest PAS setting if they don’t wish to pedal at 3000 RPMs.
Regardless, the Folding Model 1’s range of 40 to 50 miles looks great when compared to that of similar e-bikes we have tested; it is currently at or near the top of the list for single-battery folding bikes. This distance is likely to cover at least a half-day of solid saddle time, and if that amount of mileage is spread out over shorter, more casual rides, it is fair to expect a few days before needing to recharge (like me, after a gallon of coffee!).
Denago Folding 1 Review: Hill Test
Our methods for testing the Denago Folding Model 1’s hill climbing ability are described in the graphic above. It should be noted that our test hill was chosen specifically for its extreme nature; most riders wouldn’t relish pedaling up the path without motor assistance, and most motors have at least some level of difficulty reaching the top when doing all of the work.
Previously in this Denago Folding Model 1 review, I mentioned the bike’s capabilities on the short hill included in our Circuit Test – but Hell Hole was the true test of its power.
With throttle-only power, the bike steadily climbed over 1 minute and 22 seconds to reach the summit, with an average speed of 13.2 mph. This puts the bike near the top of the list when compared to similarly-specced folding e-bikes, but its PAS 5 results truly push it above and beyond.
With maximum pedal assistance in PAS 5, we flew uphill at an average of 16 mph and conquered the climb in just 1 minute and 8 seconds. How’s that for a rush?!
I personally took the bike up a variety of local hills in my testing, and to my surprise, the slope-surmounting abilities I have discussed extended to every incline I encountered. Depending on the bike I’m on, I have grown accustomed to putting in some hard work on uphill segments – but I was very impressed with the Folding Model 1’s ability to flatten just about any climb in all but its lowest pedal-assist setting.
Denago Folding 1 Review: Safety and Brake Test
The Denago Folding Model 1 uses JAK mechanical disc brakes paired with 180 mm rotors on both wheels, which also have a motor cutoff feature. With this system, the bike achieved an average stopping distance result of 19’-6”, which is barely beyond our (current) running average for folding e-bikes of 19’-0”.
We typically prefer to see hydraulic disc brakes on e-bikes capable of Class 3 speeds, but despite our unfamiliarity with the brand, we’re satisfied with the performance of the JAK mechanical setup included on the Folding Model 1.
Brakes are just one safety feature that we consider; aside from standard reflectors, the Folding Model 1 also includes a headlight and taillight with brake lights. Or, should include, rather; our test bike was a pre-production model that included the tail/brake lights, but did not come with the headlight module. As such, we cannot speak to its effectiveness or ease of use, but Denago is sending us a unit to try out. We will update this review once we can install the unit.
Denago Folding 1 Review: Ride Comfort & Handling, Cockpit, and More
In my experience, folding e-bikes are often a mixed bag when it comes to comfort and handling, and I believe that phrase accurately applies to the Denago Folding Model 1. Its pedals are standard fare on a folding bike – small, folding pedals that work fine but feel their size. I personally found the bike’s stock saddle to be too far on the firm side for my personal tastes, but it might be fine for others (and easy to replace if not). The ergonomic rubber grips, however, were a nice and comfortable addition.
As I mentioned earlier in this Denago Folding Model 1 review, the bike’s reach felt somewhat on the long side, which likely contributed to the twitchy handling caused by its extended plastic folding stem. To be clear, this feeling is not likely to be pronounced or easily distinguishable to newer riders; I imagine that it stood out to me because I have the luxury of comparing similar e-bikes back-to-back. That said, I found that the Folding Model 1 didn’t seem as stable as I’d like it to be when cornering at higher speed, but taking curves a little slower than usual made a big difference.
The small 20”x3” tires are appropriate and expected on a folding bike. These allow it to have quick and responsive maneuvering, but also don’t absorb bumps as much as larger wheels do. These days, it’s becoming less and less common to see a folding e-bike without at least some sort of suspension, so I think the Folding Model 1 would only benefit from the inclusion of a suspension fork in the future.
The bike’s cockpit layout is simple; it uses a black-and-white display that prioritizes the most relevant and important ride data. Aside from brake levers, the right bar hosts the bike’s control panel and thumb throttle and the left bar includes a Microshift thumb-operated trigger shifter. Personally, I found the throttle lever to be one of the more difficult-to-operate units I’ve tried, but the shifter to be one of the best. In particular, I liked that the same motion worked to both up- and down-shift. Finally, while it’s a simple and small inclusion, I liked the trigger-style bell included on the front brake lever. So often, I find large, hard-to-reach bells placed far away from the grips, and I liked that this one was easy to use – and it’s loud for its size!
While the Folding Model 1 ships as a Class 3 e-bike, we appreciated how easy it was to adjust the bike’s top speed. Riders who want to take the bike on more restricted paths or trails can reduce its maximum speed through its settings menu by hitting the “+” and “-” buttons on its control panel simultaneously. The bike has plenty of flexibility too, so if 25 mph is too fast for your tastes, you can quickly bring that down to 18 or 22 (or any of the other steps in-between).
Denago Folding 1 Review: Summary / Where to Buy
On the less exciting side, we would love to see a more responsive cadence sensor on the next iteration of the bike, so that the current power and initial engagement of its motor can be enjoyed throughout the rest of its riding experience. And while we appreciate the fairly broad range of riders the Folding Model 1 can accommodate, we’d also prefer to see a shorter (or otherwise more rigid) stem to provide smoother handling.
As we expected for a Denago offering, the bike delivered exciting speed and thrilling kicks between PAS settings. Unexpectedly, it also proved itself to be a biathlon champion with the endurance to sprint for hours and the brawn to climb hills with grace!
As such, we think the Folding Model 1 will appeal to intrepid travelers who want power and speed just as much as new or casual riders who might be looking for flexibility. Either way, the Folding Model 1 is a solid blend of functionality and performance in a reasonably-priced package. We’re happy to see all of that from a brand that continues to assert its competence in the e-bike market!
Happy Riding! Make sure to let us know if you have any questions down in our comments section or if you think we left anything out in this review of the Denago Folding Model 1.
Jeff says
Would the 20×3″ tires on this be good for riding on forest service roads, mostly dirt, gravel and a few trees roots?
Or could I switch them out for 4″ knobby tires easily?
John S. Bozick says
You wouldn’t be able to go up to 4″ wide tires, but 3″ knobby tires would work, and I’d probably recommend those for forest service roads. The standard tires are pretty smooth and won’t have much grip. FYI the rear wheel will be a bit tougher than the front, but it’s not a hard process.
