Tern’s HSD electric-assist bike, out of the box and on the road

by Russ Lowthian, HaveFunBiking

Every so often, I run across a truly unique bike, and the Tern HSD electric-assist bike is one bike worth checking out. Especially if you are looking for a comfortable ride with options when needing to haul cargo or a child. Looking over some of the latest electric bikes that will be available to test-ride at the E-bike Challenge Minneapolis, I had a chance to take this new Tern  cargo e-bike out for a spin

My initial test ride of the Tern HSD electric-assist bike

Using three parallel streets, on a hillside in my neighborhood as my personal test course. I had a chance to experience the pedal-assist-power and comfort of this new e-bike. On my initial ride, with close to 300 pounds of weight between myself and some extra gear, I found the bike had a smooth acceleration with plenty of power to spare. It didn’t matter if I stopped on the flat or on the 12-degree incline of the hill. Each time I started pedaling, which kicked in the motor, there were no irregular jerk movements, it was smooth. Plus, with the Bosch motor set on the Eco mode (the lowest of four e-assist settings) and the 1×9 gear drivetrain, my cadence was comfortable going up all the hills. It was also reassuring that I still had the Tour, Sports, and Turbo motor settings at my fingertips if needed.

About Tern’s HSD electric bike

THE TERN HSD ELECTRIC-ASSIST BIKE IS A COMPACT CARGO BIKE OFFERING A COMFORTABLE RIDE.

The Tern HSD P-9 is a compact cargo bike perfect for commuting, recreational riding, and running errands with some extra space to haul cargo or a child. At 5.5 feet long it is slightly shorter than the average road bike and has a load capacity of 374 pounds.

The HSD P-9 model uses a Bosch Active Line Plus motor and 400Wh battery with a Purion display, with Eco, Tour, Sports, and Turbo power settings. The drivetrain uses a 9-speed Shimano® Alivio Shadow RD cassette/derailleur. So this motor/drivetrain combination was smooth when beginning to accelerate and throughout the ride.

Bonus items that come standard

The HSD comes with a headlight and taillight. A Suntour suspension front fork to help ease bumps, 20″ wheels, an aluminum frame, Shimano hydraulic disc brakes and an integrated Abus frame lock in the rear wheel. Plus, the bike can be stored standing on its rear rack and the handlebar stem folds down flat, making it easy to fit a compact space.

THE HSD EASILY STANDS ON THE BACK RACK FOR CONVENIENT STORAGE.

Accessories

You can buy many accessories online, but Tern’s proprietary ones are fit to the bike and add convenience. Specifically, the Go-To bag that attaches to the front of the bike using a Tern Luggage Truss™ adapter. It was easy to fit my laptop inside this bag, and perfect for commuting to work, school or the library.

THE TERN GO-TO BAG COMES WITH A SPECIAL COVER FOR ADDED WEATHER PROTECTION AND VISIBILITY.

On the rear, Tern’s proprietary cargo hold panniers are weather-resistant and pack down flat. Each pannier can hold up to 60 pounds and closes securely with a magnetic clip. I found I could easily slip in two paper grocery bags on each side, nice!

What are the different types and speeds of e-bikes?

Referred to by most as an e-bike, an electric assist bicycle refers to a motorized version of the traditional bike. With three general classifications, the speeds of e-bikes vary. Compared to a regular bicycle, which relies totally on your pedal power. The electric motor assists your pedaling efforts allowing you to go farther using less energy and having more fun. The only downside to an e-bike is the added cost of the electrical system, motor, and battery lifespan. When buying an e-bike, also consider how far you’ll be riding between charges. And whether you can charge the bike’s battery at regular intervals.

A folding is ideal for commuting and touring.

Different types and speeds of e-bikes

You can use an electric bike as you would use a conventional bike. Take it on a casual city ride. Use the bike to commute to work. Or on long cross-country trips. Use the electric motor’s power to help you tackle or ascend hills by combining electric energy with mechanical gears. It is like you are mainly always riding on flat terrain.

E-trikes are also an option

Once you have defined how you will use the bike and the model you prefer, you will have to choose which of the three e-bike classifications best fits you.

Class 1: e-bikes are pedal-assist only, with no throttle, and have a maximum speed of 20 mph

Class 2: e-bikes also have a maximum speed of 20 mph but allow for throttle assistance

Class 3: e-bikes are pedal-assist only, with no throttle and a maximum speed of 28 mph.
