It compliments your pedaling, actually measuring torque output and not just pedal motion. This is because the IZIP E3 Simi is a Class 1 pedal assist product, that makes you engage and help out. Suntour makes drivetrains, suspension forks, motors, and perhaps the battery is a joint venture? In any case, the capacity is below average for the 2019 season, but should be enough to go at least 25 miles, even in the highest level of assist. It’s part of the SR Suntour drive system, which is a more widely recognized name. Powering the bike is a 36 volt 11.6 amp hour lithium-ion battery pack from Joycube. Together, they both keep the price down and reduce weight. This is a benefit when you consider the lower capacity battery pack. Overall, it’s a compact and lightweight piece of hardware that freewheels efficiently and won’t drain the battery super quick, like many of the higher powered hub motors out there. It doesn’t produce a lot of noise, even in the highest level of assist. Motor output is claimed from 250 to 400 watts with up to 60 newton meters of torque, and it was noticeable and helpful during my test climbs. Many competing hub motor systems feel abrupt and cut in and out without that smoothness. This is pretty fancy for an entry price point product, and offers a smooth natural feel. The official website says that it measures pedal torque and cadence at the bottom bracket, and I assume that rear wheel speed is also being measured. Other features include front quick release, intergraded bell, bottle cage bosses, and an adjustable kickstand.ĭriving the bike is a compact geared hub motor from SR Suntour that is “torque activated”. Mechanical brakes are great for adjustment and maintenance, however they do require a little bit more force on the levers for more sudden braking. Stopping the Simi is some Tektro 180mm mechanical disc brakes with 2 finger Tektro levers on the bars. At the pedals there is a 44 tooth chain ring with a plastic chain guide which will keep the chain steady if you happen to hit a bump or something.

For the drivetrain, IZIP opted for the entry level Shimano Tourney derailleur and a 12-28 tooth sprocket which is a bit more basic. If you want even more comfort, you could swap out the 31.6mm seat post with a suspension seat post as well. By raising the seat post, you not only get more leg extension, but you get a laid back feel from the cruiser design. The seat post is leaned back a bit which positions the saddle further back. The features, combined with the geometry shine best in smooth and relaxed riding conditions. There are a lot of comfort points on the bike, notably being the larger extra-volume Vee rubber tires (26” x 2.125”), larger comfort saddle with rubber bumpers underneath, swept back handlebars, fatter chopper style grips, and the quill stem which elevates up and down a bit and offers a 30 degree rise. The front also gets a frame mounted Fuxon intergraded headlight which is nice to see them on more electric bicycles, but truth be told, this setup is a little more basic and probably set up to keep cost down.

Mounted on the fender below the rack is a battery intergraded Fuxon rear light. Mounted to the rack is a nice big rear reflector for visibility. The rear rack is rated at 55lbs and has loops for bungie cords as well as standard tubing for panniers. The rest of the bike uses aluminum alloy for the frame, seat post, and rear rack. However, the paint-matched steel fenders could scratch a little easier. The fork is steel as is the fenders which is nice because they will not rattle as much as aluminum. The top tube has a great design which protects the battery and gives strength to the frame and reduces frame flex. The Simi, named after sunny Simi Valley in California, comes in either high-step or a step-through (which is really more of a mid-step given the frame design) and two colors a salmon color with gray accents, or a black with blue-gray accents. All new for 2019, the IZIP E3 Simi is an affordable and lightweight cruiser with comfortable riding position and an SR Suntour rear hub motor.
