I’m currently looking at the M2S All-Go. Carbon Fiber, cool looking design, stated 33 lbs with a stiff fork for $2250. I haven’t seen anything that light that comes even close to that price. The luna Bike Grit I think it’s called is in the same category, a bit cheaper but over 40lbs. I also have a significant number of stairs to haul the bike up so I’m in the same boat.
To build a lightweight electric bike is a mission full of compromises. Forget ride comfort, balloon tires, comfy seat, suspension and other niceties. Forget top speed and long range, which would require a large battery and heavy motor. Forget doing it on the cheap, because lightweight bicycle pieces are expensive. If you really want a lightweight electric bike you are going to have to pay for it with cash and ride quality…and might as well forget high performance…the only thing exciting about these bikes is their light weight…however most of these also give you stealthiness because they look like normal bikes. Because of the onset of affordable LiPo batteries and new ebike motor technologies, lightweight ebikes have become a build-able and sell-able possibility. As LiPo batteries become lighter, more powerful, and more affordable we can only expect this list to improve. We only considered complete functioning electric bikes for this list…no tiny clown folding bikes etc.
Jan, I disagree with your carry as a prime reason/not be looking at e bikes. My primary reason for an e assist is age and medical problems. Carting a heavy bike around, trying to lift it onto a vehicle would not work, and riding from home is not a possibility. I know there are light-weight e bikes out there. Price, within reason, is not a big concern. Need a 2018 update. E bikes are common in Europe, will eventually be more mainstream in the US.
There are various kinds and classifications of electric bikes on the market, but the most common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph, and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs, and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.
While we’re on this thread, I want to go ahead and throw in the most tricked-out shred sled in the AllMtn line. Haibike spared no expense wit the XDURO AllMtn 10.0. It’s a premium bike, and here is why. A Fox Factory 34 front suspension fork with 150mm of travel and Kashima coating starts things off. That’s followed by a 20-speed drivetrain brought to you by Shimano Deore XT Shadow Plus. Then you’ve got DT Swiss rims, KS LEV-DX dropper seatpost, Magura MT7 HD brakes, and a Yamaha PW-X motor. ‘Nuff. Said.
