Like the Currie, the Rayos has a lot of torque, independent human and electric drive systems, and a drive system that freewheels when not in use. The electronics shut the motor off at 80% battery discharge to avoid a full discharge (which really shortens the life of lead-acid batteries). The Rayos is an 8-speed bike that uses standard bike parts. Seats, handlebars, brakes and other non-electric parts can be found at a supercenter or bike store. Electric parts can be obtained from Rayos dealers.

And then add in all of the other e-bike parts including motors, batteries, throttles, speed controllers, etc. All of these parts are mass-produced in China. They simply aren’t available in the US and no one is designing them or manufacturing them. The US would likely have to start by reverse engineering the Chinese products and learning how they produce them. How’s that for irony?
The Stromer is tailored for riders of all types and skill levels. The patented "dual power system" allows for power-on-demand riding (limited to no pedaling), with a top speed of 20 mph and a range of up to 20 miles. Feel like pedaling? Just switch to pedal-assist mode and let the state-of-the-art torque sensor augment your pedaling efforts with motor assistance. Pedal-assist mode allows for 45+ mile range. Charging is easy with their patented removable battery system. Simply unlock the internal battery storage case on the frame, remove the battery, and charge up with any 115V power outlet (onboard charging is also available).
Older Americans, especially those 65+ are the real drivers of electric bike adoption in the United States. Betty and Grady Smith of Beaumont Texas may not know it but they are the driving demographic for electric bicycles and  tricycles. Both in thier eighties, the couple enjoys riding thier Worksman electric side-by-side tricycle around town. As a business offering electric bike and trike conversion systems since 2008, we've gotten to know...
As a counterbalance to the cute utilitarian bikes above, the Specialized Turbo Levo FSR Comp is a big, bad, and burly mountain bike. With 27.5-inch wheels, massive 2.8-inch tires, 150mm of travel in the front and 135mm of travel in the rear this bike is made to shred. The Specialized 1.3 Rx Trail-Tuned motor is designed specifically for off-road riding and features a double freehweel design that disengages the gear box at top speed to reduce friction while ripping downhill. The low center of gravity and stout parts make this one a relatively nimble handler that is ready for the rowdiest downhills.
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 Motor. Having a battery that will last long is just one piece of the puzzle. The electric motor should be powerful enough to move the bike on flat surfaces without any problems and to overcome some low-steep slopes. It will help you out on steeper slopes, it won’t let you down. If the motor or “the engine” is more powerful you’ll be able to accelerate faster and to reach a higher momentum. This will allow you to reach your destination faster and without you getting tired.
Electric mountain bikes have garnered a lot of attention for their ability to help riders go higher, further, and faster on the trail. As a result, there have been some impressive new eMTB models to hit the market in recent years, making it easier than ever to head off-road. Our favorite is the Haibike SDURO HardNine, which comes equipped with a 350-watt Bosch Performance CX drive and a 500 watt-hour battery. This gives it a range of up to 70 miles, along with a top speed of 20 mph, which is plenty fast on singletrack.
The Hanebrink all-terrain vehicle's lithium ion 10 amp hour battery (LiFePO4) will give the bike enough juice for about an hour's use on a single charge, which will take three hours. The rear rack could have up to five batteries fitted which will extend the run time to over five hours. The wide aluminum rear rack is otherwise capable of carrying over 100 pounds of cargo.
Shell Eco-Marathon Americas Competition 2015 1st and 2nd Place Winners Both Used an Electric Bike Technologies Hub Motor!

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.

At the end of the day, you'll have a ton of fun riding one. “There’s that nostalgic feeling that kicks in whenever you’re on one, that feeling you got when you started riding as a kid," LaLonde says. You might have to get on one to understand, but there are few things more smile-inducing than floating up a steep hill with little effort, Mary Poppins-style.

So instead of giving US companies breathing room to manufacture their own e-bikes, the tariffs are largely just hurting the US electric bicycle industry by preventing it from importing and selling affordable e-bikes, without solving the underlying reasons causing US e-bike companies to choose not to manufacture their e-bikes in the US in the first place.
Riese & Muller’s Nevo line definitely tops my list for commuting electric bikes. These bikes are premium, custom made bikes for a reasonable, middle-of-the-road price. All Riese & Muller bikes are hand made in Germany exactly to your specifications. The Nevo line specifically is incredibly well balanced and keeps riders in a comfortable, upright position. Riders also get a suspension seatpost (either the Cane Creek Thudbuster or Satori Elegance LT), which is a nice compromise between the full suspension Homage line and a complete hardtail.
Kalkhoff's electric-assist bicycles start with the same high-quality, sleekly designed bikes that Kalkhoff has been developing for 90 years. A state-of-the-art, brushless, centrally-located motor provides a smooth, predictable power-assist directly to the drive train. Kalkhoff e-bikes come fully-equipped with a variety of features to ensure that your commute, shopping trip, or outing is safe, comfortable and fun.
Simplicity powers the Gtech model, available in either a 20-inch “sports” crossbar frame or a 17-inch “city” step-through option. From using a carbon belt drive to a gearless system that allows a computer to adjust speed while pedaling, not only has Gtech streamlined the e-bike process, but they’ve also dropped the price to just north of $1,000. At a range of about 30 miles, this 35-pound bike offers a humble introduction to e-bikes.
Thank you Clean Republic for coming to my rescue when I had a battery issue last year. Under Warranty at 11.5 months, they without hesitation sent me an entire new $355 Battery pack when mine began to fail. I've gotten so much life, miles, and usage out of my Hill Topper from this first one and am about to replace the batteries again from so much more love on them. Seems the hub motor is going to last forever and that's what counts! Thanks guys! :)
It's what's inside your motor that sets it apart from the rest. Quality parts and assembly We've written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer's direct-drive motor. The bike was crashed and the...
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.

This bike impressed me right when I saw it. I love that Haibike offers spec-heavy options with the Yamaha PW system. I think the PW system gets a bad rep sometimes for being less powerful than the Bosch, but to be totally honest not everybody needs the power of a Bosch system. Haibike makes up for the lower torque of the PW system by offering a premium Shimano Deore XT drivetrain with 20 speeds. This is great for riders who want to stay in the action a bit more, but still not arrive sweaty and out of breath.

This thing is also kitted out with a full SRAM groupset, RockShox Yari RC front shocks, Custom Fox Float suspension at the rear and enormously punchy SRAM disc brakes at the front and rear. Fundamentally, it's a mighty off-road machine with pro-spec kit that introduces a new style of trail riding, allowing adrenaline junkies to ride further, climb harder and descend faster than ever before.
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]

A day when Alec can keep you rolling down the road and enjoying your bike is a...
Of course the specs are nuts. Shimano Deore XT Shadow+ drivetrain, Magura MT4 hydraulic disc brakes, Mach 1 rims, and Schwalbe G-One tires make this not only an incredible commuter, but really a solid racing bike if you want to challenge another ebiker. The G-One tires I just love. They’re slick enough to keep you up to speed, but have a good amount of knobiness so that you can handle bad weather.
The complete integration of the Optibike is achieved from the ground up with a disign focused on high performance, safety, and ease of operation. Front and rear long travel suspension with disc brakes gives the rider confidence. The fully integrated package gives the utmost in convenience allowing the rider to ride on road, off road and the up or down the steepest hills. Optibike is in a class of its own. The Monocoque frame has sleek styling and a low center of gravity for stable handling. All electronics and long-running battery are safely housed inside the frame.
