Functioning as their premier product, the HPC Revolution took over two years and five prototypes to get right. What’s left is a hand-welded electric mountain bike made right here in the United States featuring a 6061-T6 aluminum frame that weighs only 13 pounds and power levels upwards of 6,000W making it capable to reach speeds of 60 mph. You’ll also find its 203mm travel RockShox Boxxer World Cup Fork come in handy while off-roading as well as its Magura MT7 quad piston performance brakes when traveling at close to highway speeds.
The final appearance of both the FullSeven and the Yamaha PW-X on the countdown. This top notch 27.5″ wheeled shred sled is another perfect fire road rider for the intermediate rider looking to step their game up. One thing I didn’t mention before but I wanted to let you all know is that I think the FullSeven geometry this year allows the bikes to be more accessible to riders of all sizes. Traditionally, most companies offer one or two options for female riders. Haibike does offer the FullLife models, but the FullSeven series by and large offers better components and a very similar geometry. I think that’s great.
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.
Introducing a fully integrated, electric-assist mountain bike that takes our Altitude’s legendary handling and ride quality and adds a compact, powerful drive system. The new Powerplay™ drive system was designed in parallel with the frame, delivering ultra-short chainstays, optimised suspension kinematics, super-low centre of gravity, and class-leading torque. The result is an e-MTB that actually rides like a proper mountain bike—perfect for everything from self-shuttling all mountain trails, finding flow between the descents, and squeezing in power lunch rides. 

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.
In the 1890s, electric bicycles were documented within various U.S. patents. For example, on 31 December 1895, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with "6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel". There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery.[5]
