This is a very unique, feature rich electric bike and I’m thoroughly impressed with the component choices, custom frame and warranty… though I wish they had included bottle cage bosses, two sets would have been nice in fact! I’m glad they produced multiple size options (small, medium, large) for better fit amongst a range of rider body types, at high speed and longer distance it’s especially important to get a good fit.This is a review for the 2015 IZIP E3 Dash, in 2016 the motor was changed from a gearless direct drive hub to a mid-drive improving frame stiffness and efficiency, it dropped the twist throttle in favor of an optional $50 “boost button” that could be installed by dealers, read the full review here. One extra bonus with the TranzX system is that you can purchase a $50 boost button to add throttle on demand and the motor is so strong it will literally carry you up hills (when using the lower or mid level gears). If you want to go this route I suggest the IZIP E3 Peak or Peak DS. You could replace the hybrid slick tires with knobby ones for trail and off-road riding but it might be too much for the fork and the accessories would get rattly. The pack should charge 50%+ in the first couple of hours because the cells don’t have to be balanced (which slows charging). The range will be more limited if you ride at high speed but you could always grab an extra battery pack (at just 5.6 lbs it would be easy to stash in a trunk bag) or bring the light 1.8 pound charger along for top offs every ~35 miles or so.

The IZIP E3 Pro Tour would make a solid commuter or potentially even touring / trekking electric bike. The chainring features an aluminum alloy guide that should keep the chain on track if you encounter bumpy terrain and protect the sprocket teeth if you hop a steep curb and bash the middle of the bike. By not including a second or third front sprocket they reduced the need for tuneups, kept the price lower and focused weight-addition on the utilitarian extras… the medium sized ProTour weighed ~54 lbs which isn’t bad considering all of the included accessories. Ten speeds is just enough to hit the 28 mph top speed where the motor cuts out and SLX is one of the highest groupsets I’ve seen on any of the IZIP electric bikes. Both wheels also offer quick release for easy transport or tuneups and I love the Shimano SLX drivetrain components. I love that the frame, fork, spokes and other accessories are dark or black because it creates a cohesive mean look that also helps the cables and wires blend in (though most are internally routed). Both rims and hubs are upgraded with brass nipples, larger 13 mm spokes and thru axles (15 mm front and 12 mm rear) which should handle the increased forces of higher speed riding and the large 180 mm hydraulic disc brakes. Complimenting this are larger 700 x 45c (1 5/8″ diameter) tires, comfortable ergonomic grips and a basic seat post suspension. The ProTour delivers a nimble commuter style suspension fork that’s narrower and offers modest 63 mm travel but includes lockout adjust. This motor still isn’t as responsive or refined as Bosch but it’s much improved over earlier generations from TranzX and this keeps the price of the bike lower at $2999. I found that it operated quite well but did suffer from some mashing of the chain, sprockets and derailleur when shifting while pedaling due to the lack of shift detection and standard brake levers without motor inhibitors. The motor used here is a new one from TranzX called the M25GTS that measures speed, cadence and pedal torque to adjust power output dynamically. But it’s not especially loud, the larger chainring has a limited RPM output but offers lots of power so you really feel a boost when shifting gears up. From integrated LED lights that run off the main battery pack to a cafe style frame lock, full length plastic fenders with mud flaps, a seat post suspension, upgraded Wellgo platform pedals and a standard gauge rear rack it will get the job done rain or shine, night or day and it’s extremely fast… As a Class 3 speed pedelec it’s capable of hitting 28 mph in the highest level of assist when pedaling with the higher gears. The E3 ProTour is one of the coolest looking ebikes in the entire 2016 lineup from IZIP because the battery is integrated, the circular motor hides behind the chainring and you get every sort of accessory you could ever want to make it the perfect commuting platform.
