The ZGEXING 29-inch 48v 1000-watt front wheel conversion kit is a 1000-watt conversion kit that does something many budget conversion kits don't. When a Hall sensor fails. the controller enters a fallback mode to keep the motor running.
That is a great example of a reliable feature. You can find the current conversion kit through our amazon affiliate link.
The 1000-watt gearless motor handles daily rides with ease. If you put this kit on a 29er mountain bike you'll notice a difference in how the bike rolls compared to a standard 26-inch conversion kit. The larger diameter wheel affects the geometry of the bike and how well it tracks on the ground.
Specifications & What Comes in the Box
The ZGEXING kit comes with a 29-inch wheel mounted with a 1000-watt brushless gearless hub motor, a dual mode controller (Hall effect and non-Hall effect), a 5-speed shifter, twist throttle, pedal assist sensor, cruise control functionality, brake levers with power cut off and an aluminum alloy rim rated for 264 lbs. The manufacturer claims the motor reaches speeds of 45 to 55 km/h.
Because it uses a gearless hub motor design, there are no planetary gears that could wear down inside the motor. While this makes the motor run quietly, it also reduces long term maintenance costs. The battery is not included. You will need to purchase a separate 48-volt battery pack that is properly connected to the controller/motor combo. You will need to ensure that your 29-inch wheel is wired properly and safely to the motor/controller combination.
The 5-speed shifter works with your existing rear derailleur. However, it doesn't affect the amount of power delivered by the motor. Instead it changes the mechanical gearing ratio similar to how any standard bicycle would function. So the motor continues to deliver 1000-watts of power, but now each pedal stroke produces a different rpm on your wheel.
There is an emergency power cut-off switch located on the brake lever. As soon as you pull the brake lever shut, it kills all power being sent to the motor. This is required on every ebike conversion kit because it completely eliminates the possibility of the motor trying to fight against your brakes.

The Dual Mode Controller is Where This Kit Really Excels
While most cheap controllers just stop working when a Hall sensor fails, the ZGEXING controller will automatically switch into non-Hall mode and continue to run the motor. Using the back electromotive force voltage generated by the spinning motor, the controller estimates rotor position. It isn’t precise timing but the bike keeps running. It’s like having a spare tire on your car - you’ll be able to “cruise” on down to a shop rather than change a flat tire on the side of the road.
This reliability feature matters much more than many riders are aware because Hall sensors do fail over time. Moisture, heat and vibrations all take their toll on those tiny chips inside the Hall effect sensor. If your bike is your primary means of commuting each day, then a controller which degradates gradually rather than leaving you dead stranded on top of a hill is a legitimate feature.
Additionally, the controller also supports the five speed gear shifter which sends pulse signals to the motor controller. This allows the motor to assist based on your current gear selection giving you more assistance in low gears and smoother acceleration in high gears.
Cruise control, activated by holding the button for two to three seconds at steady speed, provides another layer of convenience for long stretches where hand fatigue becomes a problem.
Performance Characteristics
A 1000-watt gearless front hub motor is not designed to sprint. It won’t launch you from a standstill like a 1500-watt or 2000-watt motor would. According to the manufacturer’s claim, the motor reaches top speeds between 45km/hour and 55km/hour on flat ground with a quality battery pack and light rider weight. This equates to a bike that cruises comfortably within the range of 20mph to 28mph.
Since it uses a gearless hub design, there are no planetary gears to whine or grind. However, since it has less torque off the line compared to geared hubs. Geared motors punch you forward with raw torque while smooth and silent gearless motors deliver consistent power delivery.
When combining these characteristics with the larger diameter wheels used on a 29er mountain bike (which have greater rotational inertia than standard 26 inch wheels) accelerating out of a start may feel slow.
Finally, riding up hills proves to be where a front hub limitation shows its greatest effects. First, a front motor on a 29er faces reduced traction due to losses as the bike pitches backward upon climbing. Second, although the controller allows for falling back to non-Hall mode when needed, a gearless hub design does not possess enough mechanical reduction to give geared hubs an advantage during low-speed operations. Therefore, if your route contains steep grades consider adding the PAS sensor and shifting into lower gear before you begin climbing. Additionally, since PAS helps maintain cadence without relying solely on throttle power use it wisely.
The cruise control feature is nice for flats or downhills where you want constant assistance without keeping your hand on the throttle. However, keep in mind it is not a speed regulator. Set cruise at 20 mph on flats and it holds at 20 mph. Ride that same bike on a climb and speed drops because the motor does not compensate automatically. I was unable to test this myself so treat any spec numbers provided above as face value only for actual performance.
Braking Features
Brake levers come installed with integrated power cutoff sensors in case you need them quickly in order to protect yourself from being dragged by a fighting motor. Squeeze either brake lever shut immediately kills the motor's output power - which is exactly what you don't want happening on the trail. This feature cannot be disabled - it must be built into every ebike conversion kit available today in order to prevent the danger of motor-assisted braking conflict. If your frame already includes disc brakes the brake levers should fit directly - otherwise cable routing/tension adjustment may be required for your v-type brake setup.
The aluminum alloy rim is rated for 264 pounds , so most riders will be fine with it. Heavier riders should make sure their frames/forks can support additional weight from the motorized wheel , these typically weigh between 25-30 pounds for a 29in., 1000w hub motor.
The PAS sensor (pedal-assist sensor) included in the kit allows you to tap into the energy produced by your legs to help drive the motor , as you pedal harder the faster the motor assists you in propelling the bike. Additionally, since it is independent of the mechanical gear ratio you can utilize both simultaneously to provide maximum assistance for whatever situation you encounter , whether that be cruising along on level ground or struggling up steep hills.
Cruise control completes this feature list by allowing you to maintain a constant throttle output over distance without tiring your hands , perfect for extended periods spent at flat speed.
Who Should Purchase This Kit
The ZGEXING 29-inch, 48 volt, 1000 watt front hub conversion kit is ideal for anyone who owns a 29" mountain bike and wants to convert it into an electric assisted bicycle (ebike) without purchasing a brand new e-bike. This kit stands out due to its compatibility with 29ers , most affordable conversion kits come designed for 26" wheels and thus require some form of adaptation.
Reliable operation is also guaranteed thanks to the dual-mode controller , if one Hall-sensor fails then the system automatically switches to non-Hall mode ensuring continued operation , ideal for riders who rely on their bikes daily (commuters etc.).
If you value quiet operation then a gearless hub design is likely your best option , they produce significantly less noise than geared designs due to their lack of planetary gears grinding away.
However, if you are looking for pure acceleration performance or are planning on tackling very steep inclines then this kit may not be suitable due to limitations of the front hub design and 1000w ceiling.
Ultimately, if you're willing to accept slower acceleration but still desire reliable operation, then this is one of the better budget options available today.
Frequently Asked Questions
Below are answers to commonly asked questions regarding the ZGEXING 29-inch, 48v, 1000w front hub conversion kit:
What Does "dual Mode Operation" Mean for This Controller?
By default, the ZGEXING controller runs in Hall effect mode -- reading the internal Hall effect sensors located inside the motor for accurate rotor position determination. If one Hall effect sensor fails or is damaged in some way -- including wires disconnecting from said sensor or components inside the motor degrading over time -- the controller automatically drops into non-Hall mode where it uses estimated rotor position determined through back electromotive force voltage generated by the motor's rotation. While estimating isn't precision timing like Hall effect offers -- the bike continues running just fine under non-Hall mode conditions -- but sounds different while doing so.
As mentioned earlier in this article -- this reliability feature matters much more than many riders understand because Hall sensors do fail over time due to various reasons such as moisture exposure -- heat exposure -- and vibration damage caused over time.
Does This Kit Include a Battery?
No -- this kit includes everything necessary to operate except for a battery. You will still need to source your own separate 48 volt battery pack properly wired to connect with the controller/motor combo.

Can I Install This Kit on a Bike Featuring V-style Brakes?
Yes -- the ZGEXING brake levers work with both v-style brakes & disc brakes. Assuming your bike already includes v-type brakes -- simply attach them directly -- if your bike includes disc brakes -- attach them directly as well -- however depending on your specific frame configuration cable routing/adjustment may be required for proper installation.
How Does Cruise Control Function?
Press/crush the cruise control button for approximately two-to-three seconds at desired operating speed. The motor maintains that speed on level terrain until you press/crush the button again or engage brakes to cancel cruise control.
Is the PAS Sensor Included?
Yes -- the ZGEXING kit comes complete with a pedal assist sensor -- this sensor is connected directly to the controller providing pedal powered assistance based on pedaling cadence alone -- independent of twisting throttle or applying cruise control.
