For many city commuters, owning an e-bike should bring convenience — not extra chores. Greasy chains, constant gear adjustments, derailleurs clogged with road grit, and choosing between torque or cadence assist can turn daily cycling into frustration.

What if you could own a folding e-bike that shifts gears automatically, requires almost no drivetrain maintenance, and lets you toggle between two different pedal-assist styles whenever you want?
{"height":8,"color":{"hue":213,"brightness":0.83,"saturation":1,"alpha":0},"hidden":false,"locked":false,"blockName":"Spacer copy"}
That is exactly what the brand-new PVY Z20 Ultra delivers. Built for modern urban life, this folding smart e-bike combines automatic internal gearing, belt-drive simplicity and PVY’s exclusive Sensorswap Technology into one compact, city-ready package.

Drivetrain Reimagined: Auto 3-Speed Internal Gear Hub + Maintenance-Free Belt Drive
{"height":8,"color":{"hue":213,"brightness":0.83,"saturation":1,"alpha":0},"hidden":false,"locked":false,"blockName":"Spacer copy copy copy"}
The heart of Z20 Ultra’s effortless ride lies in its redesigned drivetrain, built to minimise upkeep while maximising riding comfort.
{"height":8,"color":{"hue":213,"brightness":0.83,"saturation":1,"alpha":0},"hidden":false,"locked":false,"blockName":"Spacer copy copy copy copy"}
Unlike conventional external derailleur systems, its Auto 3-Speed Internal Gear Hub houses all planetary gearing components inside a fully sealed rear-hub shell. Gear changes happen fully automatically, responding to your pedalling cadence and riding speed — no handlebar shifters required. It even supports gear-shifting while stationary at traffic lights. When you pull away from a stop, you are already in the correct gear, without grinding or mis-shifts. Shielded from rain, dust and road salt, the sealed hub drastically cuts down servicing work.

Complementing the automatic hub is a Maintenance-Free Belt Drive system. Replacing the traditional metal chain, the quiet carbon-reinforced belt transfers pedalling power without grease, rust or regular lubrication. No more oil stains on your trousers, no chain tension adjustments, and far fewer wear-and-tear issues for year-after-year reliable city riding. Together, the auto internal hub and belt-drive create a near-zero-maintenance drivetrain that changes what you can expect from a folding e-bike.

PVY Sensorswap Technology: Two Riding Modes, One Click
{"height":8,"color":{"hue":213,"brightness":0.83,"saturation":1,"alpha":0},"hidden":false,"locked":false,"blockName":"Spacer copy copy copy copy copy copy copy copy"}
Most e-bikes force buyers to pick either a torque-sensor or cadence-sensor system and stick with it. The PVY Z20 Ultra breaks this compromise by carrying the proprietary PVY Sensorswap Technology.
{"height":8,"color":{"hue":213,"brightness":0.83,"saturation":1,"alpha":0},"hidden":false,"locked":false,"blockName":"Spacer copy copy copy copy copy copy copy copy copy"}
Torque-sensor mode reads how hard you push the pedals, delivering natural, responsive motor power that feels like an amplified regular bicycle — ideal for hilly streets, busy traffic and workout-style rides. Cadence-sensor mode triggers consistent assist as soon as your pedals turn, perfect for relaxed cruising and energy-saving long commutes.
{"height":8,"color":{"hue":213,"brightness":0.83,"saturation":1,"alpha":0},"hidden":false,"locked":false,"blockName":"Spacer copy copy copy copy copy copy copy copy copy copy"}
With Sensorswap, you can instantly toggle between these two modes mid-ride. No tools, no stops. One bike adapts to your mood and route: athletic torque-sensing for weekend leisure rides, easy cadence-assist for weekday trips to work. It is equally well-suited for multi-user households, where different family members prefer distinct riding feels.

Powering the Z20 Ultra is premium 36V 14.5 Ah LG lithium-ion battery cells. Under PAS pedal assist mode, it delivers up to 120 km real-world range, more than enough for daily commutes, multi-stop city errands and casual weekend excursions. The reliable LG-sourced cells reduce range anxiety for regular riders.

Take full control via the dedicated PVY APP. From your smartphone you can adjust monitor real-time battery health, record ride statistics and customise your riding profile. Smart connectivity puts personalised e-bike settings right at your fingertips.
