Product Description

Still Small. Even More Useful.

With a 200 kg (440 lb) Maximum Gross Vehicle Weight, the GSD is ready to replace your car. It'll let you carry two kids plus groceries, or a whole lot of cargo—but it's the same length as a regular bike. Built-in dual-battery technology lets you ride all day, while space-saving features like FlatFold and Vertical Parking make the GSD incredibly easy to own and use.

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.

Electric Bike Guide

What is an electric bike? 

A bicycle with an electric motor and battery which supplements your natural pedalling power. Also known as e-bikes or pedelecs, no licence is required and you can ride them in the same places as regular bikes. 

How does an electric bike work? 

Riding an ebike is very simple, just start pedalling and the electric motor will help you along. The assist is most noticeable when starting off and climbing will seem almost effortless.  

How fast can I ride an electric bike? 

The electric motor is restricted by law to offer assistance only up to 15.5mph. You can of course ride an e-bike faster than that but you will be relying on your own pedal power over 15.5mph. 

Are they heavier than ordinary bikes? 

Electric bikes are 7 to 10kg heavier than ordinary bikes due to the extra weight of the motor and battery. You won’t really notice this extra weight while pedalling thanks to the electric assist. E-bikes handle well too as the extra weight is slung down low making them nice and stable. 

Can I vary the power output? 

Yes, the motors have different power modes so you can choose how much assist you need. The higher power modes will get you up to speed quicker but will use up the battery capacity faster.  

How far can I ride on one charge? 

The range of an ebike will depend on the battery size as well as the amount of assist the motor gives you. For example, cycling up hills requires more assist than riding on the flat. Battery capacity is measured in Watt Hours (Wh). A 400Wh battery pack will give you a range of 20 – 90 power assisted miles. While a 500Wh pack offers 30 – 140 miles 

How can I tell how much charge is left in the battery? 

The batteries have a charge indicator so you can easily tell how much is remaining. In addition to this many e-bikes have a display unit on the handlebars. This shows battery capacity as well as other data like speed and predicted range. 

Can I still ride it if the battery is flat? 

Yes, it will ride just like an ordinary bike (if a little slower due to the extra weight) once the battery is flat. You can also choose to switch the power assist off to save battery power. 

Can I take the battery off the bike to charge it? 

Yes, electric bike batteries can be charged either on or off the bike. The batteries are locked on to the bike, for security, but are easy to remove so you can charge them in work ready for the commute home.  

How long does it take to recharge the battery? 

The lithium ion batteries on most e-bike are quick to charge. A 400Wh battery pack will take about 3.5 hours to fully charge from flat. A 300Wh battery will charge in about 2.5hrs. 

What type of electric bike should I choose? 

As with any bike, the type you choose will depend on where you want to ride. The difference with ebikes is that you don’t have to worry so much about rolling resistance as the electric motor will overcome that. Up to 15.5mph an electric mountain bike will be just as quick as an electric road or hybrid bike. Road and hybrid bikes will offer an increased range however as they are more efficient.
