If you’re looking at the Duotts C29 Electric Bike, you’re probably deciding between two things: (1) is it actually a good ride day-to-day, and (2) do the headline specs translate into something you’ll enjoy (or is it overkill)?
This review explains what the published setup means in real use, what to expect from the 29” wheel format, and how it stacks up against a popular alternative: the Engwe Engine Pro 2.0 Folding Electric Bike.

Quick summary
- Best for: riders who want a big-wheel MTB-style eBike for mixed surfaces (roads, gravel, light trails)
- Standout trait: 29” wheels — they smooth out rough ground and hold speed well
- What to be aware of: mechanical disc brakes (more adjustment/hand effort than hydraulics), and a high-power setup that may not qualify as a UK road-legal EAPC
- If you want a folding alternative: the Engwe Engine Pro 2.0 is built around compact storage, fat tyres and suspension comfort
Key specs at a glance
Duotts C29 (published setup)
| Motor | 750W |
| Battery | 48V 15Ah |
| Top speed (listed) | 28 mph |
| Max range (listed) | 41 miles |
| Brakes | Dual mechanical disc brakes |
| Wheels | 29" |
| Gears | 7-speed |
| Bike weight (listed) | 26 kg |

Note: “max range” and “top speed” are typically quoted under ideal conditions. Your real results depend on rider weight, hills, tyre pressure, temperature and assist level.
How the Duotts C29 feels in real use (what the specs mean)
Motor & acceleration
A 750W setup usually feels punchy from low speed — especially when pulling away at junctions, climbing, or accelerating on gravel. The trade-off is that higher output can drain the battery faster if you ride in the higher assist levels most of the time.
Battery, range & what affects it most
The 48V 15Ah battery is a strong capacity on paper, but range is mostly decided by how hard the motor is working. If you want the longest rides, keep tyre pressure correct, use a mid assist level, and shift gears like you would on a normal bike (high cadence helps efficiency). Hills + headwinds + soft tyres are the fastest way to cut real-world range.
29” wheels: the biggest reason people choose this bike
29” wheels are a genuine ride-quality upgrade for mixed surfaces. They roll over potholes, gravel and uneven ground more smoothly than smaller wheels, and they tend to feel more stable at speed. If you’re coming from 20” fat-tyre folders, the C29 usually feels more “bike-like” and less twitchy on longer rides.
Braking: what to expect from mechanical discs
The Duotts C29 is listed with dual mechanical disc brakes. They can stop well, but compared to hydraulics you’ll typically see:
- More lever effort (especially in wet conditions)
- More frequent adjustment as the pads wear
- Bigger gains from good setup (aligned calipers + quality pads matter)
If you plan to ride fast or carry heavier loads regularly, it’s worth keeping the brakes well-maintained and checking pad wear more often.
Practical ownership: weight, load rating, charging & sizing
On the listing, the C29 is shown at 26 kg with a 150 kg max load. That’s useful if you’re a bigger rider or you’ll be carrying a backpack, lock, or commuter kit.
- Charging: listed at around 6–7 hours
- Rider sizing (listed): around 5’7” to 6’7”
- Climbing (listed): up to 15 degrees

UK legality & riding expectations
Before buying any higher-power eBike, set expectations clearly: in the UK, road-legal EAPCs are limited by assisted speed and power rules, and bikes outside those limits may require registration, insurance and the correct licence — or be restricted to private land use with permission.
If you want a bike specifically for public-road use, choose a model that is clearly sold and configured as UK road-legal. If you’re unsure, contact TrailSurge and we’ll point you at the safest option for your riding plan.
Duotts C29 vs Engwe Engine Pro 2.0 (quick comparison)
| Spec | Duotts C29 | Engwe Engine Pro 2.0 |
|---|---|---|
| Style | MTB-style hardtail, 29” wheels | Folding, fat-tyre comfort setup |
| Motor | 750W | 800W |
| Battery | 48V 15Ah | 48V 16Ah |
| Top speed (listed) | 28 mph | 15.5 mph |
| Max range (listed) | 41 miles | 72 miles |
| Brakes (listed) | Mechanical disc | Mechanical disc |
| Wheels | 29" | 20" |
| Suspension | Front suspension | Full suspension (listed) |
| Bike weight (listed) | 26 kg | 31 kg |
Which should you choose? If you want a more traditional bike feel and smoother rolling over broken surfaces, the C29’s 29” format is the appeal. If you need a folding frame for storage/transport and like compact fat-tyre comfort, the Engine Pro 2.0 makes more sense.
