We make one thing: fat-tire electric bikes.

Not because we lack the capability to build other categories. We choose focus over fragmentation.

In an industry where anyone with a factory can copy a frame, breadth is easy. Depth is rare.

Why one category?

When you make one hundred models, you understand each one 70%.

When you make one model family, you understand it down to the weld stress on a wide-tire swingarm, the battery drain curve in sub-zero temperatures, the torque response on loose sand.

That depth cannot be copied from a catalogue. It must be earned through years of doing one thing repeatedly.

What this means for our partners

Quality control that doesn't blink.

Every frame goes through 100% weld inspection. Every finished bike passes a rain test. Every unit leaves with a traceable QC record. A factory juggling 50 SKUs cannot maintain this rhythm. We can — because we only have one rhythm to keep.

Spare parts in Europe, not on a ship.

Through Smartride Supplies B.V. in the Netherlands, we stock dedicated parts inventory on European soil. When a customer in Berlin or Bordeaux needs a replacement, it ships within 48 hours — not two weeks from a container vessel. This is not a logistics achievement. It is the natural outcome of knowing one product's parts by heart.

One region, one solution.

Nordic snow edition. Southern beach edition. North American performance edition. When you truly understand fat-tire dynamics, regional customization becomes engineering — not guesswork.

Who we are

Shenzhen Qingmai Bicycle Co., Ltd. and Smartride Supplies B.V. form a China-Europe team serving brand owners, retailers, and rental operators in the fat-tire e-bike space.

We do not serve everyone. We serve partners who believe mastery beats variety — and that a long-term supplier should be a long-term ally, not just a name on a purchase order.

Let's talk.

If that sounds like the kind of partnership you're looking for, we'd like to hear from you.
