Fantastic kit !!
I've left my original revues so this review goes back in time to share my whole experiance. I was initially worried about customer service buying directly from china but don’t be, this company has fantastic customer service and always reply promptly, it’s a rare thing these days. Another update ! April 2025 Ive now done about 2000 miles and the kit is FANTASTIC ! my partner got sick of watching me disappear up the massive hills round where we live so I bought a kit for her bike too. it came on time and well packed. As it was the seccont kit id fitted it took less than an hour to fit and worked perfectly, using the app the performance of the motor in almost Infinitely adjustable, so I have set-up both bikes to have exactly the same top speed of 15.5 MPH so we don’t slowly drift apart on long runs. My partners first impression was she loved it ! We have good quality well-loved bikes that now have a new lease of life which don’t look very appealing to bike thieves especially with the battery removed (which is extremely easy) So if you have a bike you love and want to make it electric with an easy to fit high quality kit then you won’t go far wrong with this one. I can see small improvements to the kit but everything is still interchangeable which is great. The new phone holder is also much better quality than the one I was supplied a year ago >>>>>>>>>> Back about 8 months I'm now 600 miles in and still loving the kit but one morning the controller simply would not turn on. I contacted 100g.tech and as always were very prompt and helpful. the problem was with the battery cap which contains the interface to control the speed etc and the Bluetooth link to the phone. 100g.tehc sent me a link on how to remove the cap. Once removed the problem was obvious, water ingress. also the printed circuit board was not lacquered to prevent corrosion in the event of water ingress, due to the relatively high DC voltage applied to the board (40VDC) electrolitic action rapidly destroyed the board beond repair. 100g.tech immediately agreed to replace the cap and I was reqired to pay £16 in postage. (it is clear when you buy the kit you will be liable for the postage cost on any warranty parts). The new cap arrived after about 3 weeks and was simple to fit. I made sure there was a good silicon seal between the battery body and the cap. The bike is back to working perfectly and I still love it. It's worth pointing out that 100g. are not alone in having problems keeping e-bike controles watertight, plenty of the big names and expensive models are prone to these problems. I must mention I can still ride the bike! I simply put my old wheel back on and had my old bike back, not something you can do with a purpose made e-bike. >>>>>>>>>>Here's my original review<<<<<<<<<<< The kit arrived within a two weeks of the expected delivery date. I understand the delay was due to the container ship being diverted round south Africa because of trouble in the middle east. The only downside is the tracking number supplied dose not become active until it reaches the Courier in Europe. This was a bit of a worry after paying quite a lot of money. I wrote to the help line and got a helpful reassuring response from what I believe to be a human rather than a chat bot, which was a nice surprise. When the kit arrived it was well packaged and easy to fit to the bike. The tools supplied were good enough quality to carry out the job and the end result is fantastic. The transition between assist and none assists is very smooth, better than some quite expensive e-bikes I'd test ridden. I've done 300 miles so far and am expecting to do many more.
