The Shiv TT boasts an aerodynamic frame that observes the letter, but not the spirit, of the UCI's laws on position and frame shapes. Its profile has been refined in our Win Tunnel to take crosswinds in stride, and the wide range of fit options in the integrated cockpit lets riders find a fast, comfortable position for putting out power. Impressively, this is done without causing time-eating instability in tight corners or on technical descents.
One of the primary purposes of an e-bike is transferring power from the motor to the drivetrain to "support" your regular pedal stroke. All of the different motors do this in relatively the same way, although subtle differences in their power output make them all feel slightly different. It is important to note that all of these systems work impressively well, the differences between them are relatively subtle but noticeable. We tested this metric primarily based on feel, as opposed to any sort of scientific measurement, and our testers could all notice the differences between the various models. All of the e-bikes we tested have several support modes offering varying levels of pedal assist support. The Commencal and Specialized models both offer three, the Trek has four, and the HaiBike has five levels of pedal assist support. All four models also have a walk-assist setting which provides up to 3.7 mph of support in the event you have to hike-a-bike to help you push these heavy bikes uphill.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can rank you up to 28mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. Don't expect it to feel like a 16lb race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps the it nimble and agile at high speed.
The demands for the best eMTB are high. It has to climb efficiently, be comfortable to ride, be very stable and composed, yet, on top of that, be a lot of fun on the descents. Also, its integration, ease of use, and motor performance must set the benchmark. Although all the motors perform at a high level, the Bosch Performance CX is unable to keep up with the competition due to the high internal resistance it generates at over 25 km/h. It’s a pity for the Moustache Samedi Race 11: it’s by far the best Bosch bike we’ve ever ridden, but it’s slowed down by the motor. With a price tag of € 5,999, the Trek Powerfly 9 LT Plus is clearly the cheapest bike in this group test. It climbs very efficiently, but is held back on the downhills by a poor choice of tyres and slow handling – you should consider a tyre upgrade in your budget. The Haibike XDURO Nduro descends with the stability of a freight train, but it has to let the competition overtake it when going back up. With its long 180 mm travel and high weight (24.54 kg), it even feels cumbersome on the downhills.
When you are one of the top car manufacturers in the world witnessing an ever-changing landscape of reluctant buyers, what should you do? Ideally, you take scope of what works and phase out what doesn’t. GM’s bold Bolt plan was to offer the electric vehicle (EV) as a personal means of transportation and a shared mobility platform through its Maven program. We haven’t heard much from that initiative and it seems GM is ready to get in bed with the top two ride-hailing companies, Uber and Lyft. Is GM a bit lost in its strategy? Or is it figuring out what works and sharpening its vision?
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.
When all was said and done, the Commencal Meta Power Race 650B+ proved to have everyone's favorite e-bike controls. Commencal uses the Shimano Steps E8000 motor and system which features ergonomic thumb shifters, a small but easy to read digital display and a secure and straightforward charging connection. The ergonomic shifter of the Shimano system is better than the electronic buttons found on both the Specialized, HaiBike and Trek. The Commencal's best-in-the-test digital display also proved to be a favorite for its small size and out of the way mounting location, easy to read at-a-glance information, and color-coded support settings information. The HaiBike's Yamaha PW-X motor and system also featured a digital display, but testers thought it was a little too big, displayed too much information, was more challenging to read, and generally felt a little more clunky and less refined than the Shimano system. That Trek Powerfly's Bosch Purion shifter and display unit was easy to read and had a bright screen, but was in a less visible location on the left side of the handlebar. Our Editor's Choice Award winner, the Specialized Turbo Levo FSR Comp 6Fattie scored the lowest in this rating due to the lack of a handlebar mounted display and a less user-friendly charging connection.
Beach cruiser fans rejoice with the Raleigh Retroglide iE Step Thru. Cruise the boardwalk with maximum style and minimum effort as you enjoy the perks of a 350 watt motor and a top pedal-assisted speed of 20mph. Enjoy the comfort of an upright riding position thanks to the backswept handlebar and take advantage of the cargo-carrying capacity, thanks to the rear rack, to run errands around town or commute to work. With a claimed range of 35 miles, the Raleigh Retroglide is a great choice for anyone who wants to add a little speed to daily cruise.
E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.
