Some people have resting bitch face; I have resting Tern face. The minute I walk into any electric bike shop, a salesperson cannot resist approaching me. “I’ve got just the bike for you,” they say, grinning. Yes, I’ve heard of it. It’s the Tern GSD S10.
To be fair, it's probably because of my height. I’m under 5'4", which means that I'm too short to comfortably ride a lot of large electric cargo bikes. Tern, however, was founded by ex-employees of the folding bike manufacturer Dahon. Its bikes are designed to fit smaller people who live in small spaces.
Next year, Tern will release the HSD, or “Haul Stuff Daily,” bike. It’s 5.5 feet long, shorter than your average road bike and small enough to fit in Portland’s standard bike parking lots, which are 6 feet long. But it can still carry a hefty 374 pounds total—on its extended rack, front rack mounts, or a multitude of other carry options.
For two weeks, I’ve been riding a tester model to pick up my children from school and run errands. It’s fantastic, though you won't see it at a bike shop for some time.
The HSD comes in several styles and lots of colors. The base model HSD P9 will start at $3,099, but Tern sent me the HSD S8i, which starts at $3,699. It has better hydraulic disc brakes than the GSD and a weather-resistant, low-maintenance Gates Carbon Drive CDX belt (the belt replaces the chain on a regular bike), which I appreciated in this truly vile, wet, early-autumn Portland, Oregon, weather.
It’s a compact, burly bike with an upright, step-through aluminum frame. The wide, comfortable seat and ergonomic handlebars have quick releases to adjust them for heights ranging from 4'11" to 6'5".
Tern shortened the wheelbase significantly by giving the bike small, thick tires. But with an electric bike, you don’t have to worry about pedaling like a clown. The HSD S8i has a Shimano Nexus 8 hub and a Bosch 400 Wh motor. You can change up to eight gears or switch between four levels of assistance, which you can see on a tiny Bosch Purion LCD screen along with the current speed.
It’s been awhile since I’ve ridden a Bosch motor and I forgot how smooth it is. Unlike cheaper powertrain systems, it doesn’t jerk when I push off or if I've miscalibrated the level of power that I need. That smoothness is vital when you're carrying a few bags and have a kid strapped in the seat on the rack.
