ADULT BIKES

Pre-Order Dates

We do not open pre-orders for a shipment until we have a good amount of confidence in the ship date.  That being said, the estimated delivery dates listed on our website are based on the best information that we have at the moment.  While we cannot control every variable, we pledge to be honest and transparent about lead times.

- The ship dates that are on the website represent our honest estimate of the date that the bikes will ship on.

- Where information is imprecise (for example, referencing a month or quarter), it is because there are unpredictable factors that make it so we cannot credibly be more precise.

- We will work tirelessly to keep the bikes on schedule. It's part of our company culture to be very involved in our supply chain and to be proactive about addressing issues that could turn into delays.

- If something happens that changes the ship date we will communicate quickly and clearly about the delay.

- You can cancel your pre-order any time before your bike ships.


Pre-date changes

Your pre-order date will be included in your order confirmation. If we learn something that changes that date, we will contact you. You might see the pre-order date change on the website. There are a variety of things that could cause a change in the pre-order date including shipping delays, back logs, or moving through different batches. Just because the date on the website changes, does not mean that the date of a pre-order already placed has changed.  Again, if you place a pre-order and the estimated delivery date changes, we will inform you.


Pre-order payment policy

Your credit card will be charged immediately when you place your pre-order.  Your pre-order is cancelable and fully refundable. If you need to cancel a pre-order contact us and we'll take care of it!

THRU-TUBE™ Frame

The unique THRU-TUBE™ is designed to keep riders low, confident and agile. It unlocks class-leading low seat height and seat height range, and improves pedaling ergonomics while keeping the rider's feet close to the ground.

Balance-Tec™

The Zulu Two features the patent-pending BALANCE-TEC™ system, the first-ever balance-bike-to-pedal-bike conversion that doesn't compromise pedaling performance. The system's innovations include a self-extracting crank, protective bottom bracket shields that serve as footrests in balance bike mode, and an integrated chainstay key that enables chain removal and installation without breaking the chain. This proprietary design allows the bikes to be converted between pedal and balance modes in minutes without special tools while maintaining consistent handling characteristics in both configurations.

Precision Dropouts

Adjustable rear dropouts provide precise chain tension control. They also make tire changes easier by maintaining chain tension and brake adjustment during wheel removal.

Kid Optimized Cockpit

This is where little riders command these steed. It's decked out with ultra small diameter lock-on grips and short reach brake levers that are optimized for small hands.

Compact Drivetrain and Kid Size Cranks

A new smaller rear cog combined with a smaller chainring reduces weight while maintaining climbing-friendly gear ratios. The HEIR cranks have a narrow Q-factor and short length to be ergonomic for young riders.

Promax Hydraulic Disc Brakes

Powerful hydraulic disc brakes give kids plenty of stopping power on long descents.
