Performance Review: Speed, Torque, and Ride Feel
When you're investing in a 52V 2000W ebike kit, performance is everything. The KirbEbike MTX Rim Kit promises more than just raw numbers — it delivers a riding experience that’s smooth, powerful, and confidently fast. Here’s how it performs where it matters most.
Speed: 50–60 KM/H with Effortless Acceleration
Let’s be clear this isn’t a basic commuter kit. The 2000W brushless direct drive motor takes you well beyond the standard 25km/h limit (which you can toggle on or off). With full throttle or PAS 5 mode, you’ll reach:
-
Top speed: 35–38 MPH (≈ 55–60 KM/H)
-
Acceleration: 0 to 30km/h in seconds, even without pedalling
-
Cruise mode: Easily holds 25–30mph with minimal assist
Torque: 60Nm for Confident Hill Climbing
With 60Nm of torque, the KirbEbike 2000W motor gives you the pulling power needed to:
-
Climb steep city hills or backcountry trails
-
Carry cargo or ride with panniers without motor strain
-
Handle heavier riders (up to 120kg) with no drop in output
Whether you're powering up a slope or starting from a full stop at a red light, the motor doesn’t hesitate.
Ride Feel: Smooth, Stable, and Surprisingly Quiet
Thanks to its 35A FOC sinewave controller, this 2000W system delivers power smoothly and quietly. Unlike older motors that surge or buzz, the KirbEbike kit responds gradually and predictably, adapting to your riding input:
-
Quiet, gearless direct drive motor
-
Seamless PAS transitions
-
Cruise control and walk assist built into the S6 display
-
Stable performance even at top speed
Combined with the wide 39mm double-wall aluminum rim and heavy-duty 12G spokes, the wheel offers superior ride stability — even at high speeds or under load.
