Currently we sell frame kits. Complete bike builds are coming soon — sign up for updates on our contact page.

You can order directly through our online store. For custom builds, titanium frames, or large orders, contact us at sales@bikelab-inc.com before placing your order so we can confirm specifications and availability.

All prices are in USD. We accept major credit cards, PayPal, and additional payment methods depending on your region.

Yes — titanium frames can be fully customized. Reach, stack, head tube angle, seat tube angle, chainstay length, BB drop, and all interface standards can be adjusted. Carbon frames are available in standard geometry per size. Contact us for a custom quote.

Standard carbon frame kits: 4–8 weeks depending on stock. Custom titanium frames: 8–12 weeks from order confirmation. We will confirm your exact lead time at the time of order.

Yes — test rides are available at select locations. Visit our Test Rides page for current availability and booking.

Yes — we sell and ship direct worldwide. No dealers, no middlemen. Your frame ships directly from our facility in Taichung, Taiwan.

Air freight: 5–10 business days to most destinations. Sea freight: 4–6 weeks (available for bulk/wholesale orders). We will confirm the shipping method and estimated delivery at checkout.

We ship DDP (Delivered Duty Paid) — meaning duties, taxes, and import fees are included in your price. No surprise charges at delivery.

Shipping is free for end consumers worldwide — a service valued at $690 USD per frame kit or complete bike. For dealers, shipping costs are included in the wholesale price and vary by country and order type.

All frames are packed in custom-fit protective packaging designed to withstand international freight. Each frame is inspected before shipping.

All Dirtlab frames come with a manufacturer's warranty against defects in materials and workmanship. Full warranty terms are on our Warranty page.

Manufacturing defects, structural failures under normal riding conditions, and paint/finish defects. Crash damage, improper assembly, and wear items are not covered.

Yes — we offer a crash replacement program at a reduced cost. Contact us at sales@bikelab-inc.com with photos and your order details to start a claim.

Dirtlab frames are compatible with standard components and can be serviced at any qualified bike shop worldwide. For motor and battery service on eMTB models, refer to your Maxon BIKEDRIVE AIR S documentation or contact us for authorized service options.

Register your frame on our Warranty page within 30 days of purchase. You will need your order number, frame serial number, and purchase date.

We use T700 and T800 high-modulus carbon fiber in a monocoque construction process. This gives an optimal balance of stiffness, strength, and weight across the frame.

Our carbon frames are engineered and tested to exceed EN and ASTM standards for mountain bike use. Carbon is not inherently fragile — our frames are designed for aggressive enduro and trail riding.

Minor carbon damage can often be repaired by a qualified carbon repair specialist. We recommend having any impact-damaged frame inspected before riding. Contact us for guidance on our crash replacement program.

Custom color and decal options are coming soon. Sign up for updates via our contact page.

We use 3Al-2.5V titanium for tubing — the industry standard for bicycle frames, offering excellent strength-to-weight ratio, corrosion resistance, and ride compliance. Select structural areas use 6Al-4V for higher strength requirements.

Yes — this is one of our core offerings. Reach, stack, head tube angle, seat tube angle, chainstay length, BB drop, and all interface standards can be customized. Visit our Custom Frame Builder page or contact us for a quote.

Options include raw brushed titanium, bead-blasted matte, and anodized accents. Custom finish combinations are available on request.

Titanium offers a more compliant, dampened ride feel and is virtually immune to corrosion. Carbon is stiffer and lighter for the same geometry. Both are premium choices — the right one depends on your riding style and priorities. See our Titanium Process page for more detail.

The Paratu CP uses the Maxon BIKEDRIVE AIR S — the lightest full-power eMTB motor available, weighing just 1.7kg with 90Nm torque and 620W peak output.

No — the Maxon BIKEDRIVE AIR S does not thermally throttle under normal riding conditions. Unlike most competitors that cut power after 6–18 minutes of sustained climbing, the Maxon maintains full output throughout. This is one of its biggest advantages for enduro and alpine riding.

The Paratu CP is available with a 400Wh integrated battery. A 650Wh extended battery option is also available for longer rides. See our Battery System page for full details.

Range depends on terrain, rider weight, assist mode, and elevation. Use our Range Calculator for a physics-based estimate tailored to your ride profile. A typical enduro ride (1200m elevation, 80kg rider, TRAIL mode) yields approximately 35–40km on a 400Wh battery.

Yes — the Maxon torque sensor is proportional, meaning motor assist scales precisely with your pedal effort. Combined with the light weight of the Paratu CP (17–19kg depending on build), it delivers the closest feel to a real mountain bike of any eMTB system available.

We recommend sizing based on reach rather than height alone. Each bike page includes a full geometry table. If you are between sizes, contact us — we can advise based on your riding style and body proportions.

Carbon frames are available in S, M, and L — three sizes that cover the full range of riders. Titanium frames are available in XS through XXL, and can also be fully custom-built to your exact geometry. See our Custom Frame Builder for titanium options.

Carbon frames are produced in standard sizes. Custom geometry is available on titanium frames only. See our Custom Frame Builder for options.

S-Volve is our frame sizing system that optimizes reach, stack, and standover across all sizes for a consistent, proportional fit. Learn more on our S-Volve Sizing page.
