Common questions
Is the Himiway Big Dog road legal in the UK?
Yes. It is a 250W electric bike whose motor stops assisting at 15.5 mph, which makes it an EAPC — legally a bicycle. You need no licence, no tax and no insurance, you can ride it anywhere a normal bike is allowed including cycle paths, and there is no helmet requirement. The rider must be 14 or over.
How far will the Himiway Big Dog go on one charge?
The manufacturer claims 96–128 km (about 80 miles). Treat that as a ceiling rather than a figure to plan around: claimed ranges come from the lowest assist level on flat ground with a light rider, and hills, cold weather, tyre pressure and rider weight all take a bite out of it.
How long does the Himiway Big Dog take to charge?
About 7 hours from empty with the supplied charger.
How much does the Himiway Big Dog weigh?
39.9 kg. That is heavy. Fine to ride, but plan for ground-floor or shed storage: carrying it up stairs is a two-person job.
Can the speed limiter on the Himiway Big Dog be removed?
This model can have its assist limit raised, which owners use abroad where higher limits are legal. In the UK, raising the limit takes the bike outside EAPC rules: it becomes a motor vehicle needing registration, tax, insurance and a helmet, it is no longer allowed on cycle paths, and an insurer will treat it that way after an accident. We record the setting because it decides what a bike can legally be, not to suggest you change it.
Does the Himiway Big Dog have a torque sensor?
No — it uses a cadence sensor, which delivers assistance whenever the pedals are turning rather than scaling to your effort. Simpler and easier going, though less natural-feeling than a torque sensor.
What brakes does the Himiway Big Dog have?
Tektro hydraulic disc 180mm front + rear. Hydraulic discs need less hand force and hold up better in the wet and on long descents than cable-operated ones. That matters more on a bike this heavy.
How much weight can the Himiway Big Dog carry?
181 kg, including the rider. Subtract your own weight to see what is left for luggage, a child seat or shopping.

Compare with a similar bike
One tap to put the Himiway Big Dog head-to-head with a comparable eBike.
Protect your new bike
Sort these three when it arrives and you reduce the risk of theft — a good lock keeps it safe, insurance covers you if the worst happens, and registration helps you get it back.
Lock — FoldyLock Elite
A super-flexible folding lock — easy to wrap around an eBike frame and lock to almost anything. The mount doesn’t rattle, and the key slides in and out and locks smoothly (plenty of locks don’t — it saves a real headache). We run the matching pair ourselves — two locks, six identical keys, so both our eBikes open with the same key — genuinely convenient. ART 3 / Sold Secure Gold rated, the certification level many insurance policies ask for.
Insurance — Bikmo
Specialist UK cycle & eBike insurance covering theft, accidental damage and more — it’s what we use ourselves. Use our link for 5% off plus a free Komoot region.
Register — Bike Register
Log your frame number on the UK national database the day it arrives — it deters thieves and hugely improves the odds of recovery.
We genuinely use and rate these. The Bikmo link is a referral link — you get 5% off (and a free Komoot region), and it helps support the site at no extra cost to you.

Changing the assist limit — permitted use only
On the Himiway display:
- On the display, open the settings menu (typically hold M, or the +/− buttons together).
- Find the speed-limit parameter and raise it; a units setting toggles km/h ↔ mph.
- Steps vary by display — check your Himiway manual for the exact sequence.
