Posted by Eahora E-Bike on

With a growing number of electric bike models catering to every type of rider,the world of electric bikes is expanding rapidly. We have noticed that some Eahora members are not familiar with Eahora e-bikes. So we've put together a list of Frequently Asked Questions that we hear from our customers. Read on to discover what you need to know.

Electronics

Battery & Charger

 

Q: I have Juliet/Romeo Pro. My charger gets really hot when I charge the battery, is this normal?

A: Don't worry, it's normal for the charger gets hot during charging. Because Romeo has a 60Ah battery, it requires more current from the charger when it charges. You can see that the charger for Romeo is 5Ah/8Ah. Many bicycle chargers are 2Ah or 3Ah, because they only supply power to low-capacity batteries, so the charger does not need to provide as much current to the battery as Romeo does.

 

Q: Can the Juliet/Romeo Pro 48V 60Ah battery be upgraded to 52V 60Ah?

A: We do not recommend upgrading a 48V 60Ah battery to 52V 60Ah. Because 52V batteries are not compatible with 48V electronic control systems. We also do not recommend that customers upgrade their 48V electronic control system to 52V electronic control system to be compatible with 52V batteries. On the one hand it would be a huge expense. On the other hand, we have not done such tests, which can easily result in the bike not working or the electric control system burned out.

 

Q: Does the Eahora ebike battery have a USB port?

A: No, Eahora bike’s battery doesn't have a USB port.

 

Q: Will Eahora electric bike batteries be UL cerrified and approved? 

A: Yes, Eahora electric bike batteries will be UL certified and approved, you don't have to worry about their safety risks.

 

Q: I have Juliet/Romeo. Its original charger is 54.6V 5Ah, can I upgrade to 54.6V 8Ah?

A: Yes, you can upgrade a 54.6V 5Ah charger to 54.6V 8Ah, but a 58.8V 8Ah charger cannot be used as a 54V 5Ah/8Ah upgrade.

 

Q: I have a Juliet/Romeo series e-bike and it takes 9 hours to fully charge, is that normal?

A: Don't worry, it's normal. Since the Juliet/Romeo series e-bike has a 60Ah battery, that means it takes longer to fully charge. The Juliet/Romeo series battery takes around 8-10 hours to fully charge.

 

Q: What are the internal materials of Juliet/Juliet II/Romeo pro batteries?

A: Juliet/Juliet II/Romeo pro batteries are polymer batteries. It is safer than lithium batteries. Polymer batteries use polymer as a dielectric, rather than the traditional liquid medium.

The design of this solid electrolyte makes the polymer battery safer, avoiding the leakage problems that may exist in traditional batteries, and greatly reducing the probability of dangerous situations such as burning after damage to the battery. Polymer batteries have higher energy conversion efficiency, which can provide a more stable power output for the device, effectively extending the life of the device.

 

Motor

 

Q: Can I upgrade my Romeo motor to 1200W motor like Romeo Pro?

A: We do not recommend that customers do this. It can cause the bike to not work and be harmful to the electronic control system. We also do not recommend that customers upgrade their electronic control systems to be compatible with 1200W motors.

On the one hand, our technicians have not rigorously tested whether it is feasible, on the other hand, it will be a huge cost.

 

Q: Can I add an additional motor to give my Juliet/Romeo/Cupid more torque and speed?

A: We don’t recommend you do this, because after replacement, the speed of the bike didn't increase much, and we can't guarantee compatibility with the original electronic control system.

 

Q: Can I charge my bike with solar cells or a generator?

A: Of course.

 

Q: The motor of my ebike is broken. How can I replace the motor?

A: If you find that the speed of the display is not the same as the actual speed, it may be that the speed magnet is not correct. You can try setting the speed magnet to 6.

 

Q: Why my Romeo Pro/Julet II didn't live up to the advertised speed? Iit didn't even hit 20mph.

A: The Romeo Pro/Julet II has a B04U display. You can long press the "+" and "-" keys at the same time to enter the "Info" interface, and then adjust the speed in the "Speed Limit" in the "Info".

 

Q: I want my Juliet/Romeo to go faster, how do I get rid of the speed limit?

Q: I have Cupid and can't go faster than 23mph when the battery is under 40%, is that normal? Can I lift the speed limit?

A: Don't worry, when the battery's power is reduced, the speed reduction is normal. Because the battery doesn't have enough charge to power the bike. You can set P22 to 254.

Front Light

 

Q: Why can't my Juliet/Romeo's headlights be turned off manually?

A: Don't worry, the Juliet/Romeo series headlights are day-running lights. If you turn off the display, it's normal for the headlights to turn off as well. Because when our technicians developed the display and headlight, they had the safety of the riders in mind, so the headlight was set to stay on as long as the display was on. This is to avoid riders in the evening or night riding forget to turn on the headlights, causing riding safety risks.

Don't worry, the headlight use energy-saving LED lights, and the power consumption of the headlight is negligible compared to the 60Ah large-capacity battery. The battery will definitely guarantee the long range of the bike.

A: Don't worry, because the discs of the bike have not been used, some of the discs have oil, which can cause a harsh sound when braking. You can wipe the disc with dish soap/alcohol and a rag, and when you ride for a while, the harsh sound will disappear. If the harsh sound persists, you may need to replace the brakes.

Tyre

 

Q: I have Cupid, I want to know what is the correct setting range of PSI of Cupid tire?

A: In the summer, the PSI can be set within 28-30 PSI, in the winter, the PSI can be set within 35-40. The wrong PSI setting will not cause a flat tire, but we recommend that the PSI is set in the correct range and do not put too much pressure on the tire.

Align the safety lines on the left and right sides of the tire when inflating. If a flat tire or inner tube is exposed while riding, please stop riding and contact us or go to a nearby repair shop to repair it to avoid injury while riding.

In addition, we do not recommend riding in heavy rain or leaving the bike in a wet place for a long time, which is easy to damage and unsafe. If you have to leave your bike out in heavy rain, you can order a bike cover for your bike.

 

Q: I want to insure my bike. Where can I find the serial number?

A: The serial number of the bike is located on the front tube or bottom bracket of the bike. When you receive a new bike, first you can take a picture of the serial number and save it in your phone or computer, the serial number may be helpful when you want to insure the bike or the bike is lost.

 

Q: My keys are missing. What should I do?

A: The lock goes with the bike. If you still have one key, you can go to a nearby hardware store and have a second key made. If you lose both keys, you may need to order new locks and keys.

If your keys are lost and the battery cannot be removed, you will need to pick the lock in order to remove the battery and replace the lock with a new one, if you do not know how to pick the lock, you can go to a nearby hardware store for help.
