Frequently Asked Questions

You can find your wheel size printed on the side of your bike tire (sidewall). For example, in the image below it is 2.2X27.5". In this case you would order a 27.5" wheel size for your E-Switchy kit.

electric bike kit wheel size best for ebike conversion kits

E-Switchy conversion kit has been carefully designed to fit as many bikes as possible. All E-Switchy wheels are designed to be compatible with both, rim brakes as well as disc brakes.

  1. Wheel Size.
  2. Hub and Fork spacing.
  3. Fork Dropout Type.

Choosing Your Wheel Size:

We offer all of the most common wheel sizes including; 700C, 29", 27.5” 26", 24" and 20". You can find your wheel size printed on the side of the tire on your existing wheel.

Hub & Fork dropout:

Must be the conventional open type as shown in Fig.1 (U shape likely seen on most of bikes).

Fork spacing: consists of two measurements

a) Must be 100mm or 3.9 inches (standard for most bikes). To confirm fitment, check spacing of the fork between two metal arms that hold either side of the front wheel, if the space is at least 3.9" then should fit great!

b) Since the motor on the wheel is a little taller than standard non electric hubs, then you need to measure from the bottom of the forks upward 3" (above the dropout) then from that point measure across from one fork to another the distance in between should be at least 3.5" across in order for the top part of the motor not to get in contact with the fork. Refer to Fig. 2 for details.


  • If it's within the maybe category then you will most likely need to add an additional spacer(s) which are included in your kit. We have fit the wheel kits as little as 3 1/8" spacing on the top measurement but it does require adding multiple spacers on the inside of the forks.
  • Some carbon fiber frame 700C wheel size fork dropout opening (where the axle of kit drops into) tends to be slightly tighter than the standard conventional open dropout. It will still fit however, the axle width of the kit is 9.5mm or 3/8". This is the standard size for most bikes. If you have less than this size then you may need to file down the inside of the dropout in order to remove a thin layer of paint so that it can fit comfortably.

Our E-Switchy kit are 36 volts and the motor power is 250 watts. Which is just enough to clear any hill. Thanks to advanced technology and powerful zero resistance motor, we are able to make the most out of the performance. A speed of 28MPH can be reached. This is a great power for steeper hills, faster commutes & carrying bigger loads. The pedal assist is more powerful than using just the throttle. On the steep uphill, it is advised to use the pedals and take advantage of the power the pedal-assist system provides.

E-Switchy kits have a maximum speed of 28 mph

Yes! All our kits come with durable tiers. For example, on a 27.5” size wheel, you will be getting mountain bike-wide Kenda tiers. For a 700C size wheel, you will be getting road bike tiers. If you want to install your own tiers, just switch it up! Our rims can fit a wide variety of tires, everything from skinny road tires (25 mm minimum) to big 2.2" mountain tires.

Yes! You can simply turn off your battery and pedal like a normal bike. Since the kit weight is about 13 pounds total, your bike will feel the same as before and you do not have to put any extra effort in pedaling.

Yes, the kit comes complete with everything you need to complete installation, it also includes additional accessories all included. You do not need to purchase any additional parts.

Use only the provided charger. Plug it directly into the wall, do not use extension cords or power strips. Once the green light on the charger comes on, go ahead and plug the barrel end into the battery. When the charger is connected to the battery the light should turn from green to red to indicate that it is filling up the battery. As soon as the battery is full the light will turn back to green so you know it's fully charged.

You can charge whenever you like! All of our batteries are smart batteries with no memory effect, so there is no need to drain it fully before recharging like you would with older battery types like NiCad or others. Note: If you are putting the bike away for the winter or just know you won't use it for some time, we suggest charging it fully first and storing it indoors. For the absolute best life of your battery, we would also suggest plugging it back into the charger every month or so to keep it fully charged. Do not keep your battery plugged, when it’s fully charged unplug it.

If you need THROTTLE power only - select from either your LCD display or your APP power level to 0%. On the display press the bottom arrow down until you see 0% on the screen. On the APP scroll the center bar all the way left while on manual mode to read 0%. By doing this there is no pedal assist function, only throttle power!

If you need PEDAL ASSIST function - select from either your LCD display or you APP any power level 1% (anything other than 0%). This will allow the pedal assist function to be activated. You can go all the way up to 99% (lots of pedal assist power).

Note: During pedal assist function, you can always use your thumb throttle power as well if desired.

We all lost someone or know someone that has been diagnosed with cancer. We personally did, the owner of E-Switchy lost his father to panceratic cancer and this is why at E-Switchy we are determined to help find a cure of cancer especially pancreatic, we found Lustgarten foundation to be the most suitable as all donations go directly to funding the cancer research itself.

We donate a portion of each sale to a cancer foundation. By buying from us, you are aiding in finding a cure for cancer!

No, our kits do not require any PAS or Cadence sensors. This was old technology, our sensors are embedded into the motor, this innovative and advanced technology uses 6 - Axis gyroscope motion processing chip a highly sensitivity speed measuring magnets for precise speed measurements and momentum detection to ensure a very accurate power delivery based on pedaling power and road conditions.

No, you can select power up to 99%. However, for safety reasons to the rider and surrounding area we recommend 30% as the kit is quite powerful.

Follow the step by step guidance for the app setup during the initial setup video: E-Switchy LCD display and APP setup

A good way to know if your LCD display is connected properly is to open your APP home page screen and tap on "Device" at the bottom of the page. A triangle showing the a bike, a motor and a display. If all 3 are showing in green color then you know you are connected and synced.

If you are not connected then simply tap "Add Device" and it will automatically scan for your LCD display and bind to it if it's turned on.

Note: If you are connected properly, if you change the LCD display power level, it will automatically change to match the same power level automatically in the APP and vise versa.

We understand that you may want to get the best out of your kit but any modification outside of our recommendation will void any warranty to your kit.

The kit is only about 13 pounds most bicycles are about 20LB so in total your bike will weight around 33LB with battery and all accessories installed.

The LCD display throttle has a screen that shows the trip distance information, speed, battery level etc. The display also allows you to select the desired pedal assist power level directly by pressing the up or down arrow.

The manual cable throttle however you must use your APP if you want to see information such as speed, battery remaining, etc. You will also need to use the app to select the desired power level if using pedal assist function. Otherwise, the manual cable throttle if used without the APP will only provide throttle power only.


- Power set at 0% you will get throttle power only (no pedal assist function)

-Power set 1% and above activates the pedal assist function. (The throttle is still functional while on pedal assist power)

We recommend a pressure around 35PSI. As the tire will heat up while in use and will expand, over pressuring the tire will cause it to pop and may cause the rider to lose control or create injuries.

The 700C has a diameter of ETRTO 622mm. The width is 25mm from outer lip to another. An 18.7mm from the inner lip to another.
