Question 1

What is the Maxon Bikedrive AIR S and why does Dirtlab use it?

Accepted Answer

The Maxon Bikedrive AIR S is a Swiss-engineered precision motor. Maxon has manufactured precision motors for 60+ years for NASA Mars rovers and surgical robots. Independent testing measured 470W output at 150W rider input — the same tier as Bosch CX Gen 4 and Shimano EP801 — at 2,153g. It was independently confirmed quieter than the TQ HPR 60, the previous industry sound benchmark. Dirtlab is the primary global access point for this motor outside Switzerland.

Question 2

How much does the Dirtlab Paratu CP weigh?

Accepted Answer

An independent magazine test built the Paratu CP and measured 19.5kg. The motor unit weighs 2,153g — confirmed on scale and photographed. A 150mm fork build can come under 17kg. This makes the Paratu CP the lightest full-power eMTB with 170mm rear travel available anywhere.

Question 3

Why only 400Wh when competitors have 700Wh?

Accepted Answer

Independent testing produced 1,056 vertical metres at full assist from the 400Wh battery. The 600Wh battery weighs 2.8kg — 1.0kg more than the 400Wh — AND the frame structure to house it adds 0.5–0.6kg. That is 1.5–1.6kg of permanent penalty high in the front triangle on every ride. The 250Wh Range Extender (1.6kg, cage-mounted) adds 40% more range only when you need it. Total with extender: 650Wh.

Question 4

What is included in the Paratu CP frame kit?

Accepted Answer

Included: Paratu CP carbon frame (painted in your Pantone), Maxon Bikedrive AIR S motor, 400Wh battery, ANT+ HMI display, 6A fast charger, 2A travel charger, Reach Adjust headset (0/-5/+5mm), headset cups, all titanium hardware. Not included: fork, shock, drivetrain, brakes, cockpit, wheels, tyres, seatpost.

Question 5

Does the Paratu CP ship worldwide?

Accepted Answer

Yes. Frames and motor kits are always in stock raw. Lead time 3–5 weeks covers painting, QC, motor tuning, and packing. We ship worldwide from Taichung, Taiwan via DHL Express.

Question 6

Is it really quieter than a TQ HPR 60?

Accepted Answer

Yes — confirmed by independent motor test with standardised measurements in 2025. The Maxon Drive Air S is quieter than the TQ HPR 60 while assisting, and produces zero audible noise on descents due to its true freewheel design.

Question 7

What is the Dirtlab warranty?

Accepted Answer

10-year frame warranty against manufacturing defects. 2-year Maxon motor and electronics warranty. 3-year transferable warranty on resale. Crash replacement at 40% below retail for the full 10-year period. Spare parts guaranteed for 8 years after any model discontinuation.

Question 8

Is the Paratu CP SRAM T-Type compatible?

Accepted Answer

Yes. The Paratu CP uses a Universal Derailleur Hanger (UDH) dropout, fully compatible with SRAM T-Type wireless (AXS) and mechanical (Eagle 70 and Eagle 90) transmission.

Question 9

What other brands use the Maxon Drive Air S?

Accepted Answer

Very few. Outside Switzerland — where Transalpes holds market exclusivity with the E3 Enduro (which uses the same frame architecture as the Paratu CP) — Dirtlab is the primary global source. Thömus and Instinctiv are small European boutique brands. If you want Maxon full power outside Switzerland, the Paratu CP is where you find it.
