https://electricbikereview.com/haibike/xduro-fullseven-carbon-ultimate/ The Haibike XDURO FullSeven Carbon Ultimate is a 2016 version of what is now called the FullSeven Carbon 10.0. This is a high-performance electric mountain bike available in four frame sizes, stiff carbon frame for improved power transfer and handling, carbon accents include seat post, saddle, handlebar, wheelset and more. Eleven speed Shimano Deore XTR drivetrain with Di2 electronic shifting for faster, more precise gear changes and reduced chain wear, the Bosch motor controller is also designed to reduce mashing. Beautifully integrated motor and battery pack, the weight is kept low and center, shielding is minimalist but effective, unique Sprocket Equalizing System raises the chain and reduces kickback. Prohibitively expensive at ~$16k, the weight is low compared to most other ebikes I have reviewed but it wasn’t as light as I expected at ~42.5 lbs, the wheelset may only accommodate up to ~209 lbs riders.
