In order to fit a standard Bosch motor and align the chain properly, the motor has been seated to the right edge of the bottom bracket mount and a spacer has been added to the left crank arm. The frame on this thing is purpose built with internal cable routing and a custom battery motor interface. In the future, if this does present itself as an issue, maybe a lower guide will be added to the bike? Depending on the type of terrain you intend to explore, I’d approach with these considerations in mind and possibly bring a cleaning tool. Given the smaller chainring, narrow-wide teeth (that grip the chain) and tight chainring guard, would chain suck be an issue? I’m only theorizing here but it is an issue that has been brought up in the EBR forums before and fat bikes are designed for snow, sand and muddy riding. Notice how close the yolk and right chainstay are to the chain when riding in high gears… I saw the chain possibly bouncing into the joint where the yolk meets the stay in the video I shot and this gave me pause. The E3 Sumo does not have any of this additional hardware because it has a solid rear end but the chain suck thing could still be an issue. On some other Bosch powered ebikes that have rear suspension, pulley wheels and chain guides have been added to reduce chain slap, slip and kickback. In short, the motor generates a lot of power but whines a bit at high speed and can be vulnerable to chain suck if coated with mud. The chainring is much smaller than you’d normally see and is rotated at roughly 2.5x your pedal cadence making it very responsive. Electric bike shops that I visit regularly praise Bosch motors as being the most reliable… but they do produce a bit more noise than Brose due to higher RPM operation. This thing offers 75 Newton meters of peak torque output, shift-sensing and shift recommendation, as well as a compact design. Instead of using the mid-tier TranzX motor system, IZIP has opted for the top-tier Bosch Performance Line CX motor system.
