Items testing/review
Charger: (3/5)
The charger is a universal LION charger with a US plug. The rated input is 110-240V. This means US as well as other citizens (Europeans, Australians etc) will be able to use the charger. It accepts 10440 to 18650 cells and will charge cells upto 4.2V. The output is 550Mah. This will thus charge the supplied cell in about 3.5-4 hours.
The charger performed well in testing and should be good for its intended use. It has a led indicator which is RED when charging and turns GREEN when charging is done. What I did not like is that the charger looked a bit on the cheap side when compared to the other supplied components.
Battery carrier: (3.5/5)
The carrier is made of a decent quality matte finish ABS plastic. It opens at only one end. It has a spring at one end which totally prevents battery rattling while riding. It also comes with an O ring on the tail cap which should efectively prevent water ingress.
Initially I thought there was no indicator of the terminals (positive and negative) of where to put the battery but it was there. It is there. I just had to look closely!
The carrier came with a double band adhesive (to glue against your hub) and holes to insert 2 cable ties to further lock down the carrier on the axle.
I tried fitting a keepower 18650 3200Mah protected cell in it. It was a very tight fit and the battery did not even go full way inside the carrier. So tight in fact that I did not fully push it in, as the battery would have got stuck inside. Removing the outer plastic would definetely solve this problem. Unfortunately, I do not have other less capacity batteries to test.
I have another problem with the ‘design’ of the battery carrier but I fortunately have a ‘fix for it! If you use the double sided scotch provided to glue the carrier to your axle, it will not be easily removable. What a PITA. I recommend using a piece of ‘rubber’ as pictured below to have a non-sticking carrier which will allow easier removal.
Battery: (4/5)
The supplied battery is a ‘flat top’ 18650 battery. Rated capacity is 2200Mah and is a 4.2V
battery. A big plus of this non-proprietary setup is that users will be able to buy/change batteries when this one goes dead or as backup. It is shorter than the keepower protected battery which leads me to believe it is an unprotected cell. This will not be an issue in real life usage as the bike light only uses 35Ma.
I ran down the battery provided with a flashlight on high to test the charger and the battery capacity. The battery as received (no charging). I switched off my flashlight after about 20 minutes as it was getting very hot on high mode (500 lumens) with no air flow. Charging it in my Xtar VP2 took about 2 hours (from 3.6V). I would rate the specified capacity as believable. battery looks good.
A 16650 keepower protected cell was loose inside the carrier. Closing the tail cap properly locked the battery and no amount of shaking resulted into any battery rattle. This means that a number of different size LI-ION cells can be used without any problem.
Wheel light: (5/5)
That thing is oozing quality. It looks absolutely awesome. The materials used are definetely of a good standard. At the 2 end of it, are 2 holes for locking down the wheel light to the spokes.
I installed the wheel light in less than 10 minutes (sorry for the cable tie mess, I was in a hurry!). It is a very easy process. I used the default picture/animated image for testing purposes. It was an absolute pleasure. You will definetely BE NOTICED and SEEN at night. That thing is bright enough to be seen in broad day light too. The images and the animated image were perfectly displayed on the wheel. Unfortunately, the video below does not do it justice. IT DOES NOT HAVE THOSE PWM BARS. It is a camera problem. I have added a gearbest video of the light in action and it does show the product as it really runs.
Videos of the bike light in action
My video failed a bit. So I am ‘borrowing’ gearbest’s video. This is how the light actually perfoms.
My video which my camera failed to capture properly…It was tested with the factory supplied animations
Installing the unit.
This could not be easier and the supplied video from the supplied microsd card has been uploaded on youtube. It literally took about 5 minutes to get this setup.
*PROS/CONS/RELATIVE
PROS:*
– Perfect be seen light at night (This alone is a deal maker for me if you are into night riding/commuting)
– Reusable white zip ties to allow easy removing and fixing of wheel light. You are even provided a spare set.
– Programmable design can be personalised by riders for many uses.
– Great runtimes on a 18650 cell.
– Non proprietary battery/charging solution.
– Very easy to choose your custom images/animations as the software allows for any image sizes. Saves the hassle of getting images in proper size, resolution or colour.
CONS:
– The adhesive tape used to lock the carrier is more of an annoyance. There could have been a better engineered solution to allow easy removal of the carrier from the axle.
– It might be a problem fitting fatter 18650 cells in the battery carrier.
RELATIVE:
– Weight? For some weight weenies, this might be a stumbling block. If you ride/train at night, get this! The only thing that remains is a less than <50 gram plastic carrier once you remove the battery and bike light.
– Price? Honestly, for what you are getting (card reader, sd card, charger, battery and a quality product) it is reasonable. Personally, I would have bought the $28 one if on a budget)
USES:
– Be seen at night / early morning. Great for commuters, riders or people who train at night. Riders understimate the importance of side bike lighting.
– Cool factor 
You can program this thing. Personalise your rides.
– could be creatively used for advertising, displaying your name, saying someone ‘I love you’ or whatever you want to
– Excellent gifts for your kids / mates who rides.
Conclusion & Disclaimer
Honestly, if you commute at night or ride/train, this could be a welcome addition to your security for being seen. Personally, for me, the price is a bit steep at $40 but you can get its smaller brother for $28. It still is a great product for anyone wanting security, cool factor or being gifted!
Thanks for reading! If you have any querries, I can try to answer them.
