Review: Tern GSD S10 Electric Cargo Bike (3rd Gen)

With all that said, my family and I are year-round riders and live in Portland, Oregon. I live in terror that something will happen to my kids on my bike and there have been multiple times on rainy winters on hills when I have forced my much spouse to switch bikes and ride with the kids because he’s much bigger than I am and I was scared. If this is you, then you need ABS brakes. This would’ve allayed my fears quite a bit.

If safety is also one of your primary concerns, the S10 also meets the DIN 79010, the German safety standard that’s the only cargo bike standard that exists. The newly reinforced frame was tested under the DIN 79010 and verified to be safe carrying up to 463 pounds. Other components, like the rear rack, kickstand, and braking system are all tested under the DIN 79010, which is important because you don’t want the kickstand to collapse or fall while you’re strapping your baby into her Thule seat.

My kids are now 7 and 10 and ride their very own nice mountain bikes, but I did load up the panniers with mulch and wood chips and ride up and down the steepest hill in my neighborhood with about a 10 to 15 percent grade, and I felt pretty secure about its stopping power. If my kids were still pretty small, paying for ABS brakes would be a good way to extend the use of the bike through the rain.

Long-Lived

With the smart system, you’re also paying for GPS tracking if it’s stolen, locks, the Bosch eBike Flow app that connects to your phone, and customizable drive settings, so you can tweak the power settings for Eco, Tour, Sport, and Turbo.

This is important, because I have had a double battery mounted on my old Tern for so long that I forgot that the range on this is quite small. A 12-mile ride at over 20 mph depleted the battery to 50 percent in less than an hour, and I am a relatively small person (115 pounds). I would immediately put a double battery on this if you are considering it as a commuter. The Tern has a Kiox 300 Bosch display, which is easy to scroll through, but with the Flow app I would also probably just pop it off (you can pop it off!) and put my phone on a bike mount.

This may be a little hard to swallow: The bike costs $7,000, and that’s just the starting point. You will need another battery, and I guarantee you are going to want accessories, especially if you have a kid. Tern’s accessories are unmatched, especially if you have kids. I have a Storm Box, which protects my kids while riding in the rain. You can also put on a Sun Shield to protect your kids from the sun or an integrated TowBar so you can easily add a trailer.
