Tern: Vektron - 2017 Electric
Tern: Vektron - 2017 Electric
All around the world, the way we get from A to B is changing. With the world on the cusp of auto-mobility, ride sharing, and the mainstream arrival of electric vehicles, it’s an exciting moment for transportation. To help drive this force of change, we developed the world’s most compact Bosch-driven electric bike. The Tern Vektron takes everything great about folding bikes—multi-modal commuting, portability for travel and storage—and accelerates it.
It fits riders 147 – 195 cm (4’10” – 6’5”) so a single bike can be shared by the entire family.
E-SYSTEM MOTOR: Bosch Active, 36 V/250 W, max speed 25 kph (EU); max speed 20 mph (US)
BATTERY: Bosch 300 Wh (EU); Bosch 400 Wh (US)
DISPLAY: Bosch Purion, 4 mode selectable, walk assist
RANGE: up to 50 - 100 km (EU); up to 40 - 80 mi (US)
OCL+™ Frame Joint
A heavy-duty update to our iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.
Stronger by Design
Making the hinge taller and moving the pivoting surfaces outward from the center axis more than doubles overall strength and stiffness. It’s a difference you’ll feel from your very first ride.
The patented design puts four igus® bearings between the aluminum and stainless steel moving parts so the folding action is always smooth and friction-free.
The front and rear joint surfaces lock together to eliminate torsional movement.
Easy to Use
Large rounded surfaces on the lever and joint bodies are easy on your hands and allow good leverage for easy operation.
BOSCH Active Drive Unit - UNIVERSAL PERFORMANCE
Adapted from Bosch’s German-engineered automotive applications, the Active Drive Unit can take you up to 25 km per hour (20 mph in the U.S.) and operates dependably—day in and day out. Its high-performance electronics, whisper-quiet operation, and low-levels of vibration are remarkable—especially given the lightweight, ergonomic design.
3 sensors continuously monitor your pedaling power, cadence, and speed at a rate of 1,000 highly precise measurements per second. Those measurements are then fed into the motor to give you just the right amount of power based on the terrain so that your ride is smooth and natural-feeling. No sudden power spikes. Precise motor control and rapid processing of sensor signals ensure minimum levels of noise and vibration.
The well-thought-out design prevents chain derailments, thwarts improper loading, and reduces wear. An integrated stone chip and spray water protection make the drive unit extremely rugged.
BOSCH PowerPack Battery - FEATHER-LIGHT POWERHOUSE
This impressive high-energy, high-power cell carries 300 watt-hours (Wh) of power in the EU, and 400 Wh in the U.S. The best-in-class design charges fast—from zero—in only 2.5 to 3.5 hours, and lets you ride longer and further between charges. You’ll be impressed by its long lifespan, light weight, and ease of charging.
High-power density allows the PowerPack to charge to 50% in just 1.5 hours and fully in just 2.5 – 3.5 hours.
Ride nice and long between charges thanks to best-in-class energy density.
At just 5.5 lb, the weight is practically negligible during riding. The PowerPack is an ingenious balance of performance, size, and weight.
PowerPacks are designed for many tours, miles, and years of service. The integrated Battery Management System protects the battery from overcharging, undervoltage, overheating, and short circuiting.
The ergonomically designed handle makes it easy to insert and remove the PowerPack for charging. Charge it easily on or off the bike.
BOSCH Purion Control Panel - COMPACT CONTROL CENTER
The on-board computer lets you switch between five different riding modes, and feeds you handy information like speed, battery level, and distance. It optimizes shifting actions and constantly updates you on the remaining range, just like a typical German car. Best of all, it’s now more compact and robust than ever.
Valo™ Direct Light - IMMEDIATE ILLUMINATION
Our 41 lux, 150 lumen Valo Direct lights up your ride without adding the drag or weight of a dynamo. It’s engineered to sit inside the handlebar stem, where it’s safe from knocks, bumps, and theft. That means it’s protected while folding, and optimally positioned to give you the most light.
We designed the Valo with Herrmans, the Finnish lighting experts who have a side business making lights for massive earth tunneling machines. No surprise then that the Valo is ready for all weather conditions: it’s made from cold-resistant ABS with built-in water management channels.
The Valo puts out 41 lux of light, 4x brighter than the European requirement for bicycle lighting. That means you get a bright, wide beam of light that makes cycling at night safe and reassuring.
The Valo has a carefully shaped mirror that optimizes the beam pattern for cycling. It is wide, so you can see potential obstacles or hazards on the side of the road. It is even, without hotspots, so your night vision is not compromised. And it is clipped at the top of the beam pattern so you don’t blind oncoming cyclists or motorists.
The Valo has light channels on each side so that you are visible to cars approaching from the sides. For additional safety, the Valo has two additional LED’s on each side, which light up when you’re stopped at a traffic light.
Patented CryoCore™ Design
LED lights need to run cool to work optimally. If they run too hot over a period of time, they gradually lose brightness. Most LED lights have a tiny button sized heat sink that is used to dissipate heat. Our patented design connects the Valo to the handlebar so the entire bar is used as a massive heat sink.
