The Simi step-thru aluminum frame has a stylish design with curved top tube that drops down to make it easy to get and off the bike.
The step-thru height is 20″ off of the ground.
The fork is of steel construction and it is built with fender attachment points inside the fork legs.
In this view you can see the low step-thru area as well as the relaxed seat tube angle that makes it easy to stay seated while putting your feet on the ground at a stop.
The aluminum welds have a clean look and in this view you can also see how the downtube has been shaped to provide a platform for the battery.
Internal cable routing is on the left side of the downtube to provide some cable protection and a cleaner look.
Here is a look at the welds at the seat stays and seat tube junction. The rear cargo rack has an attachment at this point as well.
The SR Suntour battery is located on the downtube of the frame for central and low weight distribution. This is an ideal location for the overall handling of the bike.
The lithium battery is a 36V 11.6ah pack with 418Wh of capacity.
On the left side of the battery is the frame lock.
Once unlocked, the battery rotates to the right side of the bike for removal. Here is the downtube of the frame with the battery removed.
When the battery has been removed the bike weighs 48.4 pounds. The total bike weight with the battery is 54.1 pounds.
The battery can be charged on or off the bike. Charging time is about 4 to 5 hours for the 36V 11.6ah battery and it weighs 5.7 pounds.
Here is a look at the charger plugged into the battery on the bike.
The Suntour HESC cranks feature a 42 tooth chainring with double chainring guards to keep the chain on the chainring and to provide some pant leg protection.
The SR Suntour Performance system uses an Active Torque Sensor (ATS) to measure your riding and provide the proportional amount of assist based on the pedal assist level selected.
IZIP states “ATS simultaneously monitors the rider’s torque, cadence and bike speed to seamlessly connect the rider and bike delivering power upon demand while increasing riding range.
ATS systems have a high motor efficiency of 87%. Other systems which only monitor torque or only cadence require the motor to always be at full power requiring a larger battery to continuously deliver enough power to the system. Larger batteries significantly increase the overall weight of the bicycle which in most cases bring their bikes to well over 60lbs. which is over 20% heavier than comparable IZIP models.”
Wellgo plastic platform pedals have a large grippy platform for a solid ride feel.
A Shimano Tourney rear derailleur shifts through the 7 speed Shimano cogset.
The SR Suntour Performance geared rear hub motor provides pedal assist up to 20 mph with a peak power of 400 watts and peak torque of 60Nm.
Review Note: Each company pays a fee for a review on Electric Bike Report because of the considerable amount of time that it takes to provide an in-depth review of each eBike. A lot of time is spent on the full range test with distance & elevation profile, the wide variety of detailed pictures, in-depth video, and the write up with the specifications, ride characteristics, pros, cons, and overall thoughts. The reviews on Electric Bike Report are focused on providing you with a detailed “virtual” look at each eBike to help you determine if it is the eBike for you or not.
