With the Bosch Powerpack 400 and 500, you get convenience and access to the battery with quick removability but it’s not as hidden as the Brose batteries and some others from Easy Motion and other companies. It’s actually inset slightly and blends in with the dark gray paint. Just like the motor, the battery is mounted low and center along the downtube of the frame. The motor controller measures rear wheel speed, pedal cadence and pedal torque 1,000 times per second and that makes it perfect for navigating unstable terrain where starting and stopping is critical. It does not however, elevate the chain as a normal sprocket would and thus, the chain pully system is extra important. This empowers the motor with a mechanical advantage and allows the chain to start and stop very quickly. instead of spinning a traditionally sized chainring (or chainrings) the sprocket is smaller (18 tooth) and spins roughly twice for every pedal rotation. Thes motors aren’t silent but the high pitched whirring noise is mostly eclipsed by the knobby tires on pavement or hard packed Earth. More and more, I hear from shops that are specializing in Bosch powered ebikes because they are so reliable… but if it did fail, the motor can be replaced all at once, a new one bolted in place where the old one was.
The motor weight is positioned low and center, mounted to an integrated plate that seamlessly connects it to the seat tube and downtube. That’s a lot, it’s exactly what you want for mountain biking and is capable of steep climbs. The Bosch Performance Line CX motor offers 350 watts of nominal output but peaks above 550 and produces a maximum of 75 Newton meters of torque.
The older motor system just wasn’t as responsive or smart as this… still good, but not great. Hardware wise, I was very impressed with the new Peak DS and stunned by the price drop of $300 over prior-year model considering the upgraded motor and battery from Bosch vs. This system elevates the chain, reduces chain slap, eliminates kickback and chain slip. Further bolstering the drivetrain is an elevated chain pulley with surrounding guide and a narrow-wide tooth pattern on both the pulley cog and chainring sprocket.

This motor offers software driven shift sensing as well, so the chain, sprockets and derailleur won’t take a beating. The top assisted speed is 20 mph and it’s easy to hit with the Bosch CX high torque motor. And since it’s running a 1×11 drivetrain, shifting between gears is smoother (shorter jumps than 8 or 10) but you still get comfortable cadence options for climbing and riding fast. It’s very sturdy and serviceable thanks to 15 mm and 12 mm thru-axles with quick release and an oversized tapered head tube. With 120 mm of travel, and 27.5″ x 2.2″ tires, this is more of a cross country style electric mountain bike. The IZIP E3 Peak DS is at the top end of the spectrum with high-performance components from SRAM and light weight air suspension from RockShox.
It’s a company with good customer support, a solid network of dealers (mostly independent electric bike shops) and a whole range of products. IZIP is one of the older electric bike companies operating in the United States, they’ve been a leader in the mid-level product space for several years and are now owned by the Accell Group which has Raleigh Electric and Haibike as well.
