What tire size does the rim coming with hub motor take?
The rim we use is an oval section black double walled alloy rim, stronger than regular rims using 2.6mm chrome spokes. The rim has pad brake tracks and the wheel supports both rim and disk brake. The tire can be 20in, 24in, 26in, 27.5in, ...What brand of motor do you use in the Hub motor kit?
500W Hub motors are a customized version of MXUS XF15. 350W hub motors are an upgraded version of MXUS XF07. The motors and controllers have been redesigned and enhanced for North American standards and usage.What is the difference between 350W vs 500W configurations?
350W Motor provides 60Nm torque and 500W peak power, this is enough to power the bike up to 10% uphill climbing in pedal assist mode for an 80Kg rider. Don’t expect an ebike to climb fast without pedaling. 500W Motor provides 80Nm torque and 7500W ...Is there a scheduled maintenance on hub motors?
No, Motors are considered maintenance free unless something happens.What do parameters like Power W (Watt) mean for ebikes?
Watts is the measure of power (P) for motor. The power is important for riding faster both on flat or slope. There is a rated power definition for electric motor, which is the nominal power that the motor is designed to work to deliver efficiency and ...What do parameters like V(Volt) mean for ebikes?
Power equals Voltage by Current: The higher the voltage, lower the current is necessary to get the same amount of power (P=VI). The voltage should be managed by keeping safety and current rating of component in mind.This is a parameter which is set ...What do parameters like Ah (Ampere-Hour) mean for ebikes?
It’s the current capacity of the battery. The value is maximum current a battery can be discharged continuously for 1 hour. For example; you can draw 10A continuously from a 10Ah battery for 1 hour or 5A for 2 hours. This is a parameter that gives ...What do parameters like Ah Wh (Watt-Hour) mean for ebikes?
It’s the energy capacity of battery. Wh=Ah x V For example a 48V, 8.8Ah battery gives you 48V 8.8Ah = 422.4Wh energy which ideally means you can draw 422W power for 1 hour. The equivalent battery in 36V standard will be about 11.7AhDisk Brake Pad Replacement Types
Electric Bike Model Brake Pad Type ENVO 2019 model AVID ELIXIR type ENVO 2020 model Tektro E10.11 or A10.11 or equivalent ENVO ultra light 16inch foldable ebike AVID ELIXIR typeIs it better to replacement or rebuild old electric bike batteries?
Li-Ion battery rebuilt makes sense for the e-bikes which have proprietary battery and the replacement cannot be found. Due to uncertainties and labor-intensive process of a rebuild, it is recommended to get a new replacement battery if retrofitting ...Can I charge my ebike battery by a Portable Power Station 518Wh Outdoor Mobile Lithium Battery Pack with 110V/500W AC Outlet?
It is doable for partial charge but this setup cannot completely charge your bike. Here is an example of how to calculations based on your parameters work: Your charger normally needs about 200W input supply at 110V AC, this supply says 500W which is ...What type of cassette core do rear hub motors come with?
Here are different types of cassette. Our motor hubs have Hyper-glide cassette core which is the most flexible and common. The hub motor cassette core is for standard 7/8/9/10/11 speed cassette 34.9mm longCan ENVO motor/controller handle 48 volts battery?
Firstly note that higher voltage will only increase max speed, which will be out of ebike street legal criteria, and does not affect torque or traction. Controller is not capable of 48V but if you replace the controller with a 48V. motor should be ...What is electric bike ideal tire pressure to optimize battery performance.
It's tough to give a generalized answer to this question. It varies bike to bike, for different tires, rider's weight, application and terrain. If you inflate the tire to close to its max allowable, you will get the better battery range; however for ...Its difficult to clean the battery connectors, the contacts are hard to get at. Also what product is best for this cleaning?
It is very important to keep battery conductors clean, specially when ebike is used in a dust or dirt. Particles between battery and battery bracket conductors may cause loose connectivity, sparking resulted in melting plastic parts. How to clean? 1- ...Can I leave the battery on the bike all the time? Is turning it off after a ride necessary?
Leaving the batter on the bike is a personal preference, you should always take security of bike and battery in calculation when parking in an area with high risk of theft. If you decide to leave the battery on the bike, make sure to turn the ...If I set 0 as the assist level and turn off the display is it normal that when I turn it back on it defaults to 1?
This is a default setting on your display. You can refer to the display manual of your system to change the startup settings to land at a certain level whenever you start the system.Throttle or display malfunction after installing mirror or accessories on the handlebar

This is normal when motor is under heavy load (hills, heavy cargo) Try giving motor more assist under heavy loads Motor vibrations causing resonance on other bicycle components Reposition parts and add vibration damping between parts, make sure motor ...The throttle is not working even though pedal assist is working.
Throttle has a connection issues Check connections Throttle magnet can see interference from any nearby metal objects Try moving metal objects further away from throttleThe pedal assist is not working even though throttle is working fine.
PAS sensor is disconnected Check wires and connections for the PAS sensor or restore parameters to defaultBattery does not charge up with standard charger?
Battery is already fully charged Check battery voltage anything above 41V for 36V battery and anything above 53V for 48V battery is considered fully charged. Please refer to product manual for instructions on accessing voltage values. Charger does ...The battery cable connector is melted
Dust and dirt may cause loose connections between connection pins which can cause sparking leading up to melting Make sure to frequently keep connections clean and secured. Order replacement partsThe screen turns off and the power cuts for my ebike?
There are two main reasons for this happening. Low Charge Charge the battery and try operating the ebike once again. LCD Display connector is loose Reconnect and check all other connections inside the controller housingMy charger gets hot, should I be worried?
