Product Description

"Many e-bikes on the market look like standard bikes with motor systems and batteries wedged in," stated Josh Hon, Tern Team Captain. "We started the HSD project with the goal of designing a better, more useful, e-bike. That meant wiping away pre-conceived notions for things like frame design, riding geometry, and wheel size. The result is the HSD, a small bike that is just much more useful."

Easy to Handle
Only 170 cm long, the HSD is shorter than a regular bike. It's a breeze to handle in tight spaces and goes easily where other bikes won't. The HSD flips up for convenient vertical parking and elevator rides and can be flat-folded in seconds to go into bus racks and SUVs. 

Ready to Haul
Despite its diminutive stature, the HSD is a mid-sized cargo bike with serious hauling capacity. With a maximum gross vehicle weight of 170 kg (374 lb) and an XL-sized rack, it'll carry a week's worth of groceries or camping equipment for the weekend. It even has a dedicated trailer hitch mount, so adding extra cargo is a cinch.

The Atlas H Rack is rated to 60 kg (132 lb) and compatible with many different child seat brands, including Thule Yepp and Bobike. An upcoming Passenger Kit will allow riders to continue carrying their kids as they grow older.

Comfier For Everyone
The HSD resizes in seconds to fit riders from 150 to 195 cm (4'11" - 6'5") so everybody in the family—from teens to grandparents—can enjoy the ride. The new Easy-Step frame design offers a comfortable upright riding position for riders tall or small, as well as easy mounts and dismounts. Paired with an adjustable stem and seatpost, a suspension fork, and balloon tires, the HSD delivers a smoother and more comfortable ride even on the meanest cobblestone roads.

Safety-Ready
The HSD gets its genes for strength and durability from the GSD. EFBE Prüftechnik GmbH, one of Europe's leading bicycle test laboratories, has tested the HSD frame and fork to 170 kg (374 lb) according to their own rigorous Tri-Test standard and the upcoming EN Cargo Bike standards. In addition, the HSD is equipped with several safety features that make it ready for almost any situation: integrated front and rear lights, hydraulic disc brakes for all-weather stopping power, puncture-resistant tyres, and even reflective decals. 

Powered by Bosch
The HSD is powered by Bosch's next-generation Performance Line or Active Line Plus motors. The motors are smooth, silent, and deliver power with a wonderfully natural feeling. And of course, every motor and battery system is backed by Bosch's best-in-class warranty and service. 

A Whole Lot More
On top of all the standard features mentioned above, different HSD models are also packed with extras like Gates belt drives, Abus keyed-alike frame locks, and Cane Creek Thudbuster suspension seatposts. 

Occasionally, without notice, manufacturers change product design and/or specifications.

* 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.
