Irvine, Calif. – As eBikes transform into a "lifestyle product," smart aesthetics and attractive design play an increasingly important role. That’s why Bosch eBike Systems is setting the pace: for Model Year 2018, presenting the PowerTube 500, a battery which can be integrated into the frame of the bicycle. The PowerTube 500 combines modern design with first class Bosch technology for eBikers who prefer a clean and timeless look.
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.
The Focus comes with lots of extras: front and rear lights, bell, fenders, chain guard and rack. The Panasonic drive system that powers it is the same unit that was on the Kalkhoff bike that climbed to the top of the Pikes Peak bicycle race, one of only 3 types of bikes to survive this 8000 foot 20-mile climb in 2012. The Panasonic drive system is a well built piece of E-bike engineering which drives the bottom bracket and powers the rear wheel through the same drive chain as the rider. It is only available on OEM bikes which have been-purpose built using it. It stands as one of the most refined mid-drive systems ever built.
On a trip to Palo Alto last year, we had the chance to ride Specialized’s pedal-assisted Turbo Vado and the model is still our favorite ebike on the market. Utilizing a 350-watt motor and 604-watt-hour lithium-ion battery, the Turbo Vado is capable of traveling a whopping 80 miles on a single charge, which should be more than enough for any daily commute with plenty of miles left over.

BULLS has taken its premium frame and integrated it with the most advanced components from best names in the business. It delivers an unbelievable 118 miles range under ideal conditions. This step-over speed-pedelec is a wonder of German engineering.
The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
Installing an electric bike kit is easy to do, can be done in just an hour or so and can last for many years if done right initially. Deciding on the right electric bike conversion kit, the one that suits your riding style and your bike best, is the most important decision you’ll make during this process. Good news... you’ve come to the right place!
Electric Hybrid Bikes- As the name suggests, these bikes combine the properties of mountain and fat-tire bikes. They are built to be fast and, at the same time, tough. They are lighter than electric mountain bikes, so you don’t have to deal with the excess weight when going up hills. You can use the bike to carry heavy luggage or cycle through rough trails.
However, Emu sells a little foldable number if that's your bag. The Emu Crossbar is for town commuters that require a sweet ride that's backed up by solid Shimano Nexus hub gears and Tektro brakes, which are adequate if not the best on the market. Riding is smooth and easy, with the crank moving sensor doing its best to iron out any gaps in power delivery.
The Soho is one of Coboc’s four single-speed pedal-assist bikes. The bikes are differentiated with finishing kit - handlebar style, bar-tape, saddle and paint finish. With a retro / bespoke styling with Bullhorn bars, Brooks fabric-tape and Cambium saddle and brushed aluminium frame, the Coboc is an e-bike for riders who don’t want to look like they’re riding an e-bike. The ONE Soho is for a rider that doesn’t want gears either.
All three road bikes receive their power from Yamaha’s PWSeries SE motor that comes with four levels of support: ECO+, ECO, STANDARD, and HIGH. The mid-drive motor supplies a maximum of 70 Nm (52 ft-lbs) of torque and cadence support up to 110 rpm. The motors are designed to provide assistance up to 20 mph (32 km/h). Any faster, and it’s all you providing the power.
E-bikes are zero-emissions vehicles, as they emit no combustion by-products. However, the environmental effects of electricity generation and power distribution and of manufacturing and disposing of (limited life) high storage density batteries must be taken into account. Even with these issues considered, e-bikes are claimed to have a significantly lower environmental impact than conventional automobiles, and are generally seen as environmentally desirable in an urban environment.
Propel started in a small, second floor office with a motivating belief that electric bikes would change people’s lives, and they have. Since 2011, we have been closely listening to our customer’s needs, spent countless hours traveling and researching to learn more about ebike technology as it evolves, and we are advocating for changes in policy that promote a more equitable stake for electric bicycles in the world of transportation. Join us in this movement towards a more sustainable future; together, let’s change the way we move.

What does this mean for anyone with Stark Drive that was backed with greater then a 250W motor? Quite simply, it means that as long as you have not modified Stark Drive in any way, and depending on your local countries regulations (if they differe with this EU Standard) you are now able to use your bike legally in your location no matter where you are in the EU.
While the first electric bicycle was invented way back in the 1890s, historically e-bikes have struggled to gain momentum, only breaking into the market in mainland Europe at the turn of the 21st century. E-bikes now account for 38.5pc of all bicycles sales in Germany (Holland and France and also big players); belatedly, the trend is starting to register in the UK. Battery assisted bikes now make up around a third of bike sales at Evans Cycles West End.
