Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...
A letter from Casey Evans to Electric Bike Technologies, makers of the E-BikeKit™ electric bike conversion kit system. This one of kind adaptive electric stroller was designed by students from California State University-Sacramento using two 500w direct-drive hub motors controlled by a single E-BikeKit system. Thank you for enabling me to take my daughter hiking! My name is Casey Evans and my daughter, Montel, was born with a very rare...
With its chunky, plus-sized tires, at first sight, the E3 Peak Plus seems like a cross between a hardtail mountain bike and a fat bike. It’s good looking: the mid-drive motor and removable, lightweight battery fit in nicely with the lines of the bike, making it look more like a standard mountain bike than other models. Unlike many mid-range e-bikes, it also comes in three sizes — handy if the usual one-size-fits-all approach doesn’t fit you.
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.
The Espin is powered by a 350-watt motor that’s rated for trips up to 50 miles (depending on the terrain and assist level). Once depleted, the battery fully charges in roughly five hours. Thankfully, Espin makes it easy to remove the battery, allowing you to quickly recharge it at home or in the office between trips. A backlit LCD control hub displays your basic metrics and battery life while in transit and LED headlights add a touch of light when needed.
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle. Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.
Electric bikes are a green alternative to driving a vehicle. Studies carried out in several towns and cities show that the average car speed in rush hour traffic can dip as low as 18 to 20 mph. Electric bike speed can be as high as 15 mph. With an electric bike, you can reduce pollution, improve fitness, and still arrive at the same time as your car-bound colleagues.
On the other end of the pricing spectrum (although not as high-end as possible) falls the Riese & Muller lines. The Nevo line, which features a Bosch motor, hydraulic disc brakes and speeds up to 28 mph also has a roughly $5,000 sticker (a variety of models allows for a cheaper price). Using a carbon belt and Nuvinci grip shifter, maintenance worries lessen. The German-made premium models are hand made to specifications and comfort reigns supreme.
E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.
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,...
This 48-volt mid-motor electric mountain bike is a great value. The X-Treme Summit is packed with top-of-the-line components from Shimano, Suntour, Tektro, Samsung, Kenda, Velo, and more. With a top speed of 28 mph and tremendous torque from the mid-frame mounted motor, it conquers rough terrain and inclines like a champ. Pull power from the motor by pedal assist and throttle.
The Patriot DreamE results from the combination of the popular Day 6 bicycle with the Kinetic8-Fun mid-drive motor kit. The unique Day 6 styling eliminates leaning forward, so you sit perfectly upright. That means there is no more stress on wrists, neck, back, and crotch. It also means a superior breathing position and a better way to enjoy the scenery. The step-through design makes for easy mounts and dismounts, while the low seat allows the rider to reach the ground with both feet for stability and safety.
But with increased demand and production, as well as technology improvements thanks to advances in the electric car industry, the cost of components like lithium-ion batteries comes down, Weinert explains. Now, e-bikes are on the market as low as around $1,200 (like the Monroe 250 from Schwinn, available in November 2017). Plus, the competition is stiff. “There are more brands producing than there were five years ago, and they all have to be competitive," LaLonde says.
Yes, you read that right – north of £4k for a bike. But then, this is basically the top end of the mountain e-bike market, and you do get a lot of bike for your buck: a Yamaha Lithium battery, masterful Magura brakes, mud-slaying tyres, and – my favourite flourish of all – a hydraulic seat post that you can adjust on the move (surprisingly useful when navigating tricky downhill trails, as it means you can depress the saddle out of the way with the press of a button).
Upper Dublin Township in Pennsylvania is initiating a pilot project to gauge the advantages of using electric bicycles. The e-bike, as they are more commonly known, will be used for police work and for the Township’s Sitewatch program, which patrols and monitors parkland and playing fields. The people behind the program believe the electric bike could prove to be a useful tool, giving police officers and parks personnel a clean,...
At speed the E proved a stable and neutral ride, the motor engaged in good time and there was a reasonable amount of assist (the amount of motor assist is adjustable via a Bluetooth app up to 25kmph or 15.5mph). Charging of the in-hub battery is possible via a neat hollow charging bolt on the drive-side of the rear wheel. The Cooper E is one for retro-futurists and people who want others to say, "No way that’s an electric bike!"
Over the years our lineup has grown, and as a result, the offering has become more complicated than it needs to be. Specifically, this year we introduced a 500w geared motor option to the lineup and that has created some redundancy. Before outlining changes, we would like to ensure everyone that we will be stocking enough inventory of previously sold parts for a long enough time to ensure all warranties...
Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle's crankset. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bicycle's standard drive train.
E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
