The speed range of the motor itself is somewhat limited but it’s very powerful which is great for climbing and it’s fairly quiet. To truly reach ~28 mph on this electric bicycle you do have to pedal along and use one of the higher gears.
MODIFING A IZIP E3 DASH TO A NEW BATTERY FULL
This plastic ring has three buttons… one to enable boost, one to slowly and smoothly reach ~6 mph and another unlabeled button offering full power up to ~20 mph if you’re using one of the higher gears. While this is a speed-pedelec Class 3 with only pedal assist by default, you can spend $50 extra for a boost button to be mounted near one of the ergonomic grips. The 10 speed Shimano Deore drivetrain is solid mid-level and should hold up well if cared for. It’s a more basic motor that does not detect shifting and therefor may strain the chain, sprockets and derailleur more if you try to shift while pedaling hard and using a high level of assist. I found the motor to respond mostly to cadence, to run quietly and to be slightly delayed… both starting and stopping. You get thru-axles for improved stiffness (12 mm rear and 15 mm front) and hydraulic Shimano disc brakes with a larger 180 mm rotor up front for quick stops. This improves balance and frame stiffness while making quick-release on both wheels possible (and easier). The 2016 IZIP E3 Dash features a high torque mid-drive motor while the previous two iterations used gearless direct drive hub motors.
