Carries Your Family
Our ecosystem of passenger-carrying accessories fits your family—now, and five years from now. Carry two little ones in child seats and watch as they grow into (and out of) the Clubhouse. Give your spouse a lift on date night with the Captain's Chair. Snap a photo of the day your teen graduates to carrying you.
One Size Fits Most
The GSD has an adjustable cockpit that resizes in seconds and without tools to fit riders 150 - 195 cm tall (4'11" - 6'5"), so you can easily share it with your family. The updated frame geometry with a slacker seat tube angle and higher handlebars also means the GSD doesn't just fit—it's more comfortable too.
Cargo-Ready
The GSD is made to fit your life, including all your stuff. Our ecosystem of accessories includes a wide range of cargo-carrying gear designed to keep your loads secure and stable for wobble-free hauling. You may not have thought of using a bike to pick up groceries, home improvement supplies, or plants for your garden—but now you will.
Easy to Manage
The GSD's unique geometry makes for super stable riding, no matter what you're hauling (or how wiggly your kids are). The low center of gravity lets even smaller riders confidently manage heavy loads, and the step-thru frame makes getting on and off the bike a breeze. Plus, we've made it easier for the rider's feet to reach the ground at stops.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.

Tern GSD S10 Gen2 500wh Performance CX LX 2023 - Electric Cargo Bike
Long story that involved a bike being wronglly shipped, a loooooooonnnnggg return process, or rather refund process to release a new bike for me. All staff were very friendly and dealt with my endless queries. . We're all impatient nowadays when in reality 2 weeks from cock up.to fix is not bad and with compensation. Sometimes things go a little wrong but it was no ones fault really. TNT courier company are not good but I suspect they're the cheapest. Overall I'm happy with bike set that arrived well packed and I will use tredz again.
