8 reasons not to buy

  • 20” wheels and an aluminum frame can make for a harsh ride.
  • With two batteries, a GSD could weigh almost 70lbs.
  • Flat-resistant Schwalbe tires could be unforgiving and bouncy.
  • The 20” front wheel felt a little sketchy to one reviewer.
  • While representing a sound investment, the GSD is expensive.
  • This small frame felt undersized, to one 5’8” reviewer.
  • A reviewer of small stature had trouble getting the GSD into a vertical position.
  • While the S00 comes with an integrated Abus wheel lock, the S10 does not.

Bottom line

Owners called the Tern GSD a great investment and a complete car replacement. It moved quickly and easily hauled an adult rider, two children and cargo up steep hills. Kids’ seats, panniers and other accessories are readily available. Its small size and vertical storage capability makes it perfect for apartment living. With two batteries, maximum range was extensive. Handling was nimble. Negative reviews are hard to find. While expensive, most reviewers noted the savings on fuel, maintenance and taxes offered by the GSD.

Tern GSD Review

Tern’s GSD is in a class of its own — it’s a folding electric bike with huge cargo and kid carrying capacity that stands on its rear end. And it’s amazing.

Review: Tern GSD S10

…if your goal is to reduce the number of trips that you make by car, the GSD S10 is the best way I’ve found… It handles and feels the most like a commuter bike of any cargo e-bike that I’ve tried.

Bike Test: Tern GSD S10 Electric Cargo Bike

Yes, you could buy a (secondhand) car for what the GSD costs. But the running costs are thousands of pounds apart… The more you use the e-bike, the more you’d save… It’s hands down the most useful e-bike I’ve ridden.

Tern GSD: An e-Bike The Whole Family Will Love

I was never a cargo bike kind of guy… Besides being a badass grocery hauler, I loved bringing my son out on the bike. He couldn’t stop smiling and laughing… The little dude was actually saddened to see the bike go and said “why don’t you just buy one.”

48 Hours with the Tern GSD

Getting Shit Done (GSD, get it) is really what Tern’s electric utility bike is about. It replaces a car, an SUV, and whatever you want to do because it has a 150-mile range.
