The KBO K1 eBike is a budget folding e-bike with a 500W motor, a battery of about 500 Wh and a 20 mph limit. Reviewers rate it as good value for casual riders and first-time buyers. Real-world range is lower than the 45-mile claim, so plan around about half of that.
How We Built This Guide
We did not ride the bike ourselves. This guide compiles published tests from Rider Guide, CleanTechnica and WebBikeWorld.
Where sources disagree, we say so. Prices and specs change, so confirm them on the maker's site before you pay.
KBO K1 at a Glance
- Best for: apartment dwellers, car-boot commuters and beginners.
- Launch price: $699 in 2024, according to Rider Guide.
- Frame: step-over. Its sibling, the K2, is the step-through version.
- Warranty: two years, according to WebBikeWorld.
- Biggest caveat: the motor is loud, and real range is about half the claim.
KBO K1 Specs and Features
| Feature | Reported spec | Source |
|---|---|---|
| Motor | 500W rear hub (Bafang; 750W peak, per WebBikeWorld's K2 review) | Rider Guide, WebBikeWorld |
| Battery | 48V, 10.4Ah (about 500 Wh), removable | Rider Guide, WebBikeWorld |
| Claimed range | Up to 45 miles | CleanTechnica, Rider Guide |
| Top speed | 20 mph, Class 2 | Rider Guide |
| Assist | 5 modes, cadence sensor, throttle | Rider Guide |
| Weight | 48 lb without battery; 55 lb with battery | WebBikeWorld |
| Tyres and fork | 20 x 3 in tyres, front spring fork | Rider Guide |
| Brakes and gears | Mechanical discs (160 mm), Shimano 7-speed | Rider Guide |
| Rider weight limit | 280 lb | Rider Guide |
| Safety certification | UL 2849 (electrical system) | Rider Guide |
Sources differ on small details. Rider Guide lists a rear rack carrying about 60 lb, while a forum summary of KBO's spec sheet says 55 lb. Rider Guide lists a tail light, but the same forum summary says the launch model had none.
Performance: Motor and Speed
A 500W motor is generous at this price. Rider Guide notes that bikes this size often carry only 250W or 350W motors.
The tester saw 23–24 mph on the speedometer going slightly downhill. After allowing for speedometer error, he put the real top speed near 21 mph.
The controls are straightforward. CleanTechnica says you can set the maximum speed anywhere from 6 mph to 20 mph.
Battery and Real-World Range
KBO promises 45 miles. Rider Guide says it typically sees around half of any manufacturer's stated figure in its tests.
So budget for roughly 20 to 25 miles of mixed riding. Heavy throttle use, hills and a heavier rider will cut that further.
Charging safety matters too. The K1's UL 2849 certification covers the electrical system, according to Rider Guide.
Ride Quality, Folding and Comfort
The K1 is nimble and solid. Rider Guide's 6'1" tester, who weighs over 200 lb, found it slightly small but stable.
CleanTechnica's reviewer, a self-described late middle-aged woman, expected trouble and found the size just right. That is a useful range of opinions.
What testers liked
- Wide 3-inch tyres add cushioning and grip on light trails.
- The bike sprints away quickly once the motor engages.
- Fenders, a rack and a bell come as standard.
- The battery sits in the downtube and locks in place.
What testers did not like
- The motor is a little loud and vibrates, which rattled the metal fenders.
- It can take a couple of pedal strokes before the motor kicks in.
- Suspension travel is small.
- A cadence sensor suits casual riding, not fitness training.
Pros and Cons at a Glance
| Pros | Cons |
|---|---|
| Low price for a 500W, 48V bike | Real range is about half the claim |
| Folds small for flats and car boots | Motor noise and fender rattle |
| Fenders, rack and bell included | Limited suspension travel |
| Two-year warranty | Cadence sensor, not torque sensor |
| UL 2849 certified electrical system | Spec details vary between sources |
UK Buyers: Check the Law First
The K1 is sold as a US Class 2 bike. UK rules are stricter.
According to GOV.UK, a legal electric bike (EAPC) must meet these points:
- Motor output of no more than 250 watts.
- No motor propulsion above 15.5 mph (25 km/h).
- Pedals that can drive the bike forward.
- A rider aged 14 or over.
A 500W bike that exceeds these limits may be classed as a moped or motorcycle. Ask the seller to confirm compliance in writing before you buy.
Who Should Buy the KBO K1?
A good fit if you:
- Want a first e-bike on a tight budget.
- Need to store it in a small flat or carry it in a car.
- Ride short city trips or light trails.
Look elsewhere if you:
- Want quiet, refined power.
- Plan long daily rides beyond 20 miles.
- Want a bike for fitness-focused riding. Rider Guide points to torque sensors and mid-drives for that.

Buyer's Checklist
- Confirm the current price on the seller's page.
- Check the stated rack limit and whether a tail light is included.

- Check your local e-bike laws, using GOV.UK if you live in the UK.
- Measure your storage space against the folded dimensions.
- Confirm your weight fits within the 280 lb limit.
