I’m not sure if it would be an issue here but the 10 speed Shimano Deore drivetrain felt great and offers good mid-level performance. I did notice some clicking and sticking, however, and have heard some riders in the UK comment on chain suck for some Bosch drive systems. This keeps the chain on track, reduces slips, and helps to protect your pants. IZIP took an additional step to keep the motor functioning properly by using a narrow-wide tooth chainring and adding an alloy bash guard/guide. It’s sleek and compact in appearance but still has an Aluminum alloy skid plate along the bottom to protect from rocks and other obstacles. Note that the motor is tipped up, built into the downtube and seat tube, and uses minimal plastic shielding. It’s great to have a second source of less biased feedback saying the motors are good too, and that’s what the shops do. I often wonder about long term maintenance because my ride tests are short and usually company marketing reps are on hand to make sure there are no problems. Shops all around the US tell me that Bosch is reliable and my experience with the product has been good. So the motor is rated at 250 watts nominal but peaks above 500 watts and is one of my favorites. You don’t have to think about clicking an arrow for more or less assist, it just does its own thing. One moment you’re pushing softly because the ground is hard packed and smooth, then you’re pushing harder to scale a rocky incline… and the motor responds naturally. It’s perfect for “Just riding” when you’re in varied conditions like trails. What eMTB mode offers is a full range of power output and a torque sensor feel. It’s their high-torque CX model which is rated up to 75 Nm peak output and now features eMTB mode if you get your shop to help upgrade the software to the latest version. The seat post is fairly long and highly adjustable, measuring 31.6 mm in diameter, this post is a bit sturdier than the traditional 27.2 mm and could easily be swapped out for a seat post suspension like the Suntour NCX for improved back and neck comfort.ĭriving this electric mountain bike is an internally geared centerdrive from Bosch. And regardless of size, notice the sloping top tube which allows easy stand over. And the bike comes in two frame sizes! Some of the mid-level lower priced electric bikes forego sizing because it costs more, but I feel that IZIP hit a perfect balance here with price and options. Ground clearance is also higher to deal with rocks and other obstacles one might encounter on the trail. Drive system weight is positioned low and center, where you need it for optimal handling and clearance. I immediately noticed how custom the IZIP E3 Peak+ frame was on this bike, notice the custom tubing for inset battery and angled motor. Note that the pack requires a bit of effort to push and click onto the frame, especially when it’s new. Both batteries are compact, can be charged on or off the bike, and are easy to carry around thanks to a little loop at the top. In addition to looking great, the new Bosch system is forward compatible to work with the latest Powerpack 500 battery as well as the original Powerpack 400 which is included with the Peak+ here. The previous model used a TranzX M07 motor which just measured cadence and didn’t feel as fluid. Ultimately, if you shift properly, you get more range per charge and the bike rides more naturally. The motor controller measures wheel speed, pedal cadence, and pedal torque 1,000x per second making it one of the most efficient systems I have tested. Moving from TranzX to Bosch brings shift detection which reduces drivetrain wear, faster pickup, and a lighter battery. The price did rise $300, but in my opinion, it looks a lot better and is definitely using a smarter, more durable electric drive system. IZIP completely updated their hardtail trail bike, the Peak, going from the 2016 season to 2017.
