Our verdict

Runjia suits riders in the US looking for an off-road electric bike with a throttle, a removable battery and a mid-drive motor, sold direct and through dealers. The entry model starts at $1,399, and the Duo Ride bundle reaches $3,999, so a pair costs more than a single bike.

Pros and cons

Pros

  • A throttle and a removable battery are both listed, so the bike can be ridden without pedalling and the pack charged away from the frame.
  • The off-road model pairs a claimed range of 161 km with a payload ceiling of 386 kg.
  • Finance is available, in line with the 96.7% share of brands in this group.
  • A frame warranty of 2 years and a 14 day return window take some risk out of buying.
  • The spec sheet lists hydraulic disc brakes and ul 2849 certification.

Cons

  • Support runs on email and help centre, with no phone line listed for problems that need talking through.
  • The battery is covered for 1 years against 2 years on the frame, so the pack ages out first.
  • Shipping is listed for US, a single market, so anyone outside it needs a different seller.
  • Weight starts at 55 kg, so the bike is loaded into a car rather than carried up stairs.

Who it suits

  • Riders in the US who want a throttle and a removable battery for off-road use and are content to sort servicing by email.
  • Shoppers who want hydraulic brakes and a listed certification at a modest outlay rather than the bike range Kalkhoff lists as IMAGE 3 MOVE, Endeavour 5+ Move, Entice 7+ Advance ABS.
  • Couples or friends buying together, since the Duo Ride bundle at $3,999 is priced as a pair.

Who should look elsewhere

  • Buyers outside US, who should compare Kalkhoff or Tern, since Runjia lists a single market for shipping.
  • Riders after a folder or a cargo bike for carrying loads, who should look at Tern with GSD R14, Quick Haul D8, HSD P10e, Vektron P7i instead.
  • Anyone wanting longer battery cover, since Runjia protects the pack for 1 years against 2 years on the frame.

How it compares on our data

On the entry figure, Runjia sits at 96 in a field of 149 brands. The top of the range reads differently: 108 out of 145. The bundle is what moves this brand on the upper figure, so the pair is the expensive way in. Buyers who need a single bike can read the entry figure and set the rest aside, and anyone shopping bundles should compare that higher number against what a second bike costs elsewhere.

Core features

The bikes in BIBUFF GT600, BIBUFF G7 carry a throttle, so they can be ridden without pedalling, and a removable battery, so the pack can be carried off the frame. Claimed range is 161 km, and payload reaches 386 kg. The lightest listed weight is 55 kg, which makes this a bike to load rather than one to carry upstairs. The frame is covered for 2 years and the battery for 1 years, with 14 days to send a bike back. Finance is available.

Plans and prices

The entry bike, one of BIBUFF GT600, BIBUFF G7, is the way in at $1,399. The Duo Ride bundle sits at the top of the range at $3,999. Each figure is the price of a bike or a bundle of bikes rather than a plan that renews, so the cost is a single outlay and nothing recurs afterwards. Budget from the entry figure, and treat the gap up to the bundle as the price of a second machine rather than as a fee.

The company behind it

Runjia sells as Runjia International Trading Limited, with its base in Hong Kong. After the sale, help runs on email and help centre, so questions are handled in writing or through the help centre rather than over the phone. That is worth weighing for a bike meant for rough ground, where setup and spares questions tend to come up early.

Frequently asked questions

What does a Runjia e-bike cost, and does the price cover one bike or a set?+

Each figure is a price for a bike or a bundle of bikes, not a plan that renews, so the outlay is a single one. The entry model, one of BIBUFF GT600, BIBUFF G7, sits at $1,399, and the Duo Ride bundle is priced at $3,999. Treat the gap between them as the cost of a second machine.

How far does the battery go and can the pack be taken out?+

Claimed range is 161 km for the off-road model. The battery is removable, so the pack can be lifted off and charged somewhere other than a garage, which matters if the bike lives in a hallway or a flat upstairs. Read the figure as a maker's claim, since real distance on loose ground is usually shorter.

Is there a throttle, and where does the motor sit?+

Yes, a throttle is listed, so the bike can be ridden without turning the pedals, and the battery is removable. The motor sits in the middle of the frame rather than in a hub, the layout used by the Kalkhoff models listed as IMAGE 3 MOVE, Endeavour 5+ Move, Entice 7+ Advance ABS. Mid-drive puts the weight between the wheels, which changes handling on loose surfaces.

How heavy is the bike and what can it carry?+

The lightest listed weight is 55 kg, so the bike is loaded into a car or carried down steps rather than lifted up them. Payload is capped at 386 kg, which covers a rider plus gear and leaves room for a passenger or a long day out. Check both figures against your own storage arrangements before ordering.

What does the warranty cover and can the bike be returned?+

The frame is covered for 2 years and the battery for 1 years, so the pack is the shorter of the two. Returns run for 14 days, a short window beside a shop that lets you ride for a month. Finance is available if you would rather spread the cost than pay the entry figure in full.

Where does Runjia sell and can the bike be bought in person?+

Sales run direct and through dealers, the sales model listed as both. Shipping is listed for US, a single market, so anyone outside it would need a different seller. The company behind the brand is Runjia International Trading Limited, based in Hong Kong, which matters for warranty work and for who handles a return.

How do buyers get help after buying?+

Support runs on email and help centre, so questions travel by email or into the help centre, with no phone line listed. On an off-road bike the practical questions are about setup, charging and spares, so it is worth working through the help centre before ordering rather than after something has gone wrong.

Can the cost be spread out over time?+

Yes. Finance is available, which lines up with most brands in this group. Whether it helps depends on the rate and the term, and those are set at the point of application rather than listed with the bike. On a tight monthly budget, weigh the finance terms against the entry figure of $1,399 before committing.
