This step-through frame will make your commuting life or weekend errands infinitely easier, with speeds of up to 20 miles per hour and an electric assist motor that will power you for up to 50 miles. The Evo Eco Lite rides smoothly and handles like a normal bike—and looks like one too, thanks to careful battery and motor placement. Front and rear fenders plus a rear rack make it easy to ride to work, the library, or the grocery store. It has a simple app to go with it, but you can upgrade to the Premium app, or add a GPS Tracker, a winter battery cover (for snowier climates), or a lighting cable as extras.

Available for FREE on over 30 VBT vacations, our electric- assisted E-bikes provide extra help whenever you want it—riding uphill, extending your range at the end of a long day, or simply letting you ride together with partners of different abilities. E-bikes work with your own pedaling, silently reading your exertion and augmenting it.
[…] you need to pedal to move, but the eBike senses your assistance needs and the motor provides the ideal amount of propulsion. Experts agree this is the more intuitive of the two types as its senses your needs based on your […]
Say you’re a responsible 20 mph max rider using proper power, but someone idiot car driver opens their door and you have no time to avoid the whack! You don’t have a helmet on (which is the law in Calif. using power assist). On a regular bike the idiot car driver would be liable for your injuries. Since you weren’t wearing a helmet their insurance rep could argue court you were negligent and broke the law…hence your brain injury was YOUR fault, not the car driver. Same would happen if they discover you monkeyed with the max. speed sensor…or the max power level.
Luckily regardless of the laws, I dont hear much about them being enforced anywhere. For example ebikes are completely illiegal in NYC and people still ride them there all the time, and in fact the city has probably the most successful ebike store in the country: nycewheels
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection – our Direct-Drive motors are now all High-Torque 6×9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the…
Built with durable e-bike rated components, the Archer is ready for trails and pot-holes. The oversized axles and adjustable suspension provide a confident feel as you race down the trails or streets.
E-bike usage worldwide has experienced rapid growth since 1998. In 2016 there were 210 million electric bikes worldwide used daily. It is estimated that there were 120 million e-bikes in China in early 2010, and sales are expanding rapidly in India, the United States of America, Germany, the Netherlands, and Switzerland. A total of 700,000 e-bikes were sold in Europe in 2010, up from 200,000 in 2007 and 500,000 units in 2009.
We also crossed the 1kWh barrier by combining it with 21 Ah capacity. This is 95% more range than the standard e-bike battery. We added real-time GPS tracking and topped it off with a 8A fast charger capable of special programmable charging protocols that allow for over 1,500 recharge cycles to be extracted from your lithium battery.
Some assembly of your new electric bike may be required. Often, this merely involves attaching the front wheel, but assembly chores are sometimes more complex than that. Several manufacturers provide instructional videos to help owners with the task of e-bike assembly.
Interestingly, it appears that if I wanted to, I could also ride it as a moped. In the example, 36V makes it go 23-MPH. With 48V, it would go about 28-MPH, and have about one and a half horsepower. As a moped, note that it does not require the bike to have pedals. As a motorized bicycle, it IS required to have fully operable pedals.
The ShippingPass assortment is continually being optimized. Products are added and removed for lots of reasons, but the main reason is to show items that we’re 100% sure we can deliver within the promised timeline.
Size: Some electric bikes look a little small, but if you’re going to drive to the edge of the city and ride the last couple of miles, a light, folding model that you can easily throw in the trunk has definite advantages.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider. Some manufacturers, such as the Canadian BionX or American E+ (manufactured by Electric Motion Systems), have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains. The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
Compared to the torque sensor system, the cadence sensor will just provide the assist based purely on the level assist you have selected and it will not increase or decrease the assist based on your actual pedal power. You could be pedaling very lightly or very hard and it will provide the same level of assist.
An all-wheel drive electric fat bike with adjustable drive modes (rear, front or both with traction control), beautifully integrated battery and compact motors blend in making it stealth. Upgraded quick release and thru-axle design makes the rear wheel easier to remove and the……
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!

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.
This Saturday, Oct. 7, Tim Sway will showcase his “UpTriCycle” at the Greater Hartford Mini Maker Faire. Sway calls the UpTricycle an “off grid, electric, solar charging mobile maker space and carrier for upcycling makers.” He uses minimal tools and footprints in his creation for unlimited potential. On his YouTube page, Sway made a comparison video between a gas-powered trike and an electric trike. He purchased a gas-powered trike first,…
