The control panel is instead positioned under the top tube, helping to reduce impact and wear in the event of a crash or tip. Operating this bike is relatively simple as the handle bars don’t feature any electric-specific dashboards or switches to mess with or be distracted by… just the standard brake levers and trigger shifters. If you keep the pack stored in neutral temperatures and top it off after each use your batteries will last for more cycles and if you’re carrying the frame on a hanging-style car rack removing the battery will make it easier to mount. I like that you can take the pack off relatively easily because that significantly reduces the overall weight of the bike (the battery pack casing weighs ~20 pounds with the controller also contained inside). It has a keyed lock for security and a built-in handle for easier carrying. This pack is capable of 50 miles per charge in the lowest assist level and is even removable with a quick release lever just below the top portion of the downtube. Powering this bike is an enormous 36 volt 20 amp hour Lithium-ion pack positioned in the main triangle space of the frame. The motor is fast, strong and loud but quite durable and very responsive. The system is a bit more complex than a modern bottom bracket mid-drive such as that used on the Bosch systems because you’ve got two drive trains to manage (belt and chain) but this reduces strain on the chain and sprockets and the rear wheel still features a quick release which makes it easier to work with than many hub drive systems today. Basically, your pedal power and the motor power both go into this differential and can propel the bike forward. The motor pulls a Gates Carbon belt drive that connects with a planetary differential hub in the rear. As mentioned earlier, this ebike is capable of putting out enormous torque which is perfect for accelerating or climbing, even with gear. The motor driving the Express is a 750 watt high speed canister configuration that sits just behind the seat tube and is encased in a translucent plastic container extending from the battery and controller case in the main triangle. a smooth power output due to a super-sensitive servo actuated speed sensor and the overall weight due to the large battery capacity. With great components and a solid warranty this electric bike could be a good fit for commuters but the big downsides include the louder noise it produces when riding (as shown in the video review above), a bit of “surging” vs. The Express was designed from 2008 to 2012 when it was delivered to the LAPD and has since become available to the public through Currie Technologies at a sale price of ~$2,800. I believe the LAPD still has some of these bikes but their use is limited due to the overall weight of the system at ~62 lbs which can make transport and carrying up/down stairs difficult. The bike achieves that and more with a top speed of ~28 mph and well balanced custom battery/motor combination that puts out 92 Newton Meters of torque (higher than any other ebike I’ve tested to date). The goal was to create an ebike that could withstand the varied terrain of an urban environment, transport equipment and gear easily and last an entire day without running out of batteries. The IZIP Express Special Edition is a purpose built electric bike that was originally designed for the Los Angeles Police Department (LAPD) Bicycle Patrol Unit.
