The Electric Fat-Tad Recumbent Trike is built regularly for customers of www.ElectricTrike.com by Electric Bike Technologies in Croydon, PA. If you already have a Sunseeker Fat-Tad and wish to convert it on your own, or if you wish to buy one locally to convert on your own, the following may help as guide to your conversion. If you would like to purchase the kit and add-ons used in this conversion, you can...
Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.
This is a question the designers and engineers of the FOCUS and BULLS bikes of this group test asked themselves. Instead of speccing them with the standard 500 Wh batteries, both have developed a sophisticated alternative. The idea: instead of riding around with unnecessarily large batteries and unnecessary weight on short tours, they integrated a smaller 375 Wh or 378 Wh battery into the bike. If you don’t have enough power for long loops, you can double the range of both bikes with an additional battery for up to a full 750 Wh. While the second battery is mounted in the front triangle of the FOCUS, it disappears sideways in the downtube of the BULLS. In practice, you’ll need the second battery relatively often with both bikes, and in either case, you should consider the additional € 499 investment in a second battery pack when you buy the bike.

On mine I got the Topeak front and SKS rear mud guards, an Axiom rear rack, front and rear lights. They didn’t have a headlamp with the lumens I wanted, so Tommy the owner went ahead and ordered one for me! He was always available for any question I may have had through his mobile phone, and updated me with pictures showing me different possible setups to see if I would like it.

The removable 460 Wh battery is hidden in the downtube, and the custom-built-for-Specialized Brose motor is integrated around the bottom bracket, and develops 250 watts of power. A torque sensor detects when you’re applying pressure to the pedals, and provides assistance when you need it. Aside from the glowing green LEDs indicating charge levels and output settings, there is little indicating this Turbo is anything but a typical mountain bike. 


Getting an e-bike can dramatically increase how often you ride, according to a recent survey of nearly 1,800 e-bike owners in North America. Beforehand, 55 percent of respondents said they rode daily or weekly. After buying an e-bike, that number soared to 91 percent. It makes sense: Even if you’re super fit, you still get tired (likely from training or racing) and remounting your bike can feel like a chore. If you have an e-bike, you can continue riding while giving your knackered legs a bit of a break. You can also go faster, which makes biking for longer trips more attractive, even when you’re pressed for time.

It’s hard to ignore the growing popularity of electric bikes. Commuters and hybrid riders have already embraced the technology, but what about when it comes to mountain shredders? MTB fans are certainly beginning to realise the benefits of electric – an electric mountain bike can give you all the thrills you want from a normal MTB but with the extra power you need to get back to the top and give the trail another go.


Our twelve-person test team not only tested the most exciting eMTBs of the 2018 season in the cold German winter, but also took them to the south of France for two weeks (we will spare you the mandatory muddy photos at this point). We climbed to the top of peaks, rummaged through deep mud, rode over countless roots and ruts on the way up and even more on the way back down, laughed, cursed, lived through many unforgettable moments, and took the bikes – and sometimes ourselves – to the limit.
Fat E-Trike from Sun and E-BikeKit™ at Interbike 2014 Fat bikes and electric bikes were all the rage this year at interbike in Las Vegas. It seemed almost every bike vendor at the show has at least one fat bike model in their booth this year. On top of the fats were the electric bikes. And I think it goes without saying that nobody wants to actually pedal a fat...
Over several months, our team of four professional mountain bike testers rode each of the electric mountain bikes in our test selection on a variety of trails and terrain in a range of weather conditions. We had each tester ride each of the bikes numerous times, often riding the different models back to back for the sake of comparison. We didn't go easy on them. Instead, we treated them all as if they were our own, putting them all through the wringer to identify their strengths and weaknesses. We scrutinized every aspect of each e-bike's performance and scored them all on several rating metrics, e-bike controls, downhill performance, uphill performance, power output, and distance range. Each metric are described in greater detail below. It is important to note that during our testing our impressions of these e-bikes changed dramatically. Our first impressions didn't exactly stick. It was essential for us to test the different models head-to-head and make direct comparisons to flush out the differences. For example, everyone was initially a little underwhelmed with the Specialized's power and more excited about the Haibike, but after hundreds of miles of testing our impressions changed. We go into more detail on this below.

The quality of electric mountain bikes is changing dramatically. We set out to find the best ones you can buy today. After looking at 15 models, we narrowed it down to four in the $5,000-$5,500 price range. We then took to the trails. Over the course of several months, our team of testers rode these e-MTB's for thousands of miles and hundreds of hours to find out how each model performs on the trail, which one has the longest range, the most power, and most user-friendly controls. We rode these bikes hard, scrutinizing every aspect of their performance, exposing the strengths and weaknesses of each. We present our findings here in this detailed comparative review to help you find the model that's right for you.
China's experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes.[2] As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.[2]
Just take a look at the Kenevo and you know it wants to go fast. Downhill. And probably destroy every turn it sees. The tank-like aesthetic and aggressive geometry does indeed allude to the bikes intended purpose. If downhills are your thing, the burly Kenevo is your friend: it’ll get you to the top with ease but, once the seat drops, you won’t be able to stop it. There’s not a lot more to be said about it – the best in its class…
As my boys were growing up in the 2000s, we would bike together in local parks and I always dreamed of taking them on my favorite big rides when they reached their teenage years. But in 2012 I started getting sick and I didn’t know why. Two years later, after countless doctors visits, tests, and head scratching, I received some bad news from my doctor: somewhere in my adventures, I had contracted Lyme Disease. My life has never been the same.
A 2008 market survey showed that the average distance traveled in the Netherlands by commuters on a standard bicycle is 6.3 kilometres (3.9 mi) while with an e-bike this distance increases to 9.8 kilometres (6.1 mi).[79] This survey also showed that e-bike ownership is particularly popular among people aged 65 and over, but limited among commuters. The e-bike is used in particular for recreational bicycle trips, shopping and errands.[79]
My left crank arm came loose and seems to have damaged the square bottom bracket mount. I assumed the bottom bracket was just a standard square taper, but noticed it says “8fun” on it. However, I can’t seem to find an 8fun bottom bracket available online, so I can’t figure out what part I need—I suspect there is a something obvious that I’m missing. Any ideas to get me back on the road? Thanks all.
As the CleanTechnica series has been showing, electric bikes are an increasingly big business, and becoming the dominant form of motorized two-wheel transportation globally. The innovation, design, and money is flowing to electric bicycles much more than motorcycles. This is part and parcel of our increasing urbanization and demographic shifts globally. Electric bikes just make sense. They shorten commutes, they flatten hills, they make groceries and children light, they are fun, and they are clean, silent, and convenient.
The first step in deciding which Electric Bike is for you is to determine the right style for your type of riding. Want to take things off road? We have a full range of Mountain Electric Bikes, Hunting Electric bikes, and  Fat Tire Ebikes that’ll have you going on and off trails with ease. Looking for a low impact but super fun ride? Our line of Comfort E-bikes, Commuting E-bikes, and even folding bikes will have you zipping around town, on the beach, or anywhere you can ride- no problem.
