Great company, excellent customer service every single time and great product!
Delivered item as advertised. After a month of intermittent use, still happy with performance, haven't even had to charge the battery yet.
Very responsive customer service through the chat feature online, and delivery was quick (within 1 month). I converted my Brompton using this kit 3 months ago now and haven't looked back! I like the fact I can still fold up my Brompton as normal with battery installed. The OLED handlebar display is an add-on worth having for convenience of adjusting power assist level on the go. Shaved 8 minutes off my commute! It is a great product, easy to install (good installation videos online) and so far have had no issues.
Great customer service from Gina at 100G. Had a few tech questions and they were answered accurately and quickly. Delivery was way faster than expected
Very helpful communication and really quick service.
This part was for replacing a failed part after 1y of usage. Good advices, good video, it worked as told, just the transportation is slow and despite the parts is free, the transport is not. Anyway this kit is working well with few equivalents for my need, retrofitting my long range trekking bike, because my 50+ long experience in being young biker.
Good quality, some of the rubber accesoires to tighten the bottle are poor quality. Also the key bottle lock is poor quality. But overall very pleased by the quality of the motors and bottles
100G had exceptional good service - quick reactiontime and helpful advice. unfortunately I received a different controller than I had before so my light cables wouldn't fit anymore. had to wait two more weeks for the cables to arrive. after attaching the cables the new controller who had worked properly wouldn't work anymore. 100G requested a video from me - I only sent a picture because nothing worked/moved anyway...
Hello, thank you for sharing your experience objectively. We sincerely apologize for our mistake of missing the light cables in the initial shipment, and we sent you the replacement cables free of charge as soon as possible afterwards. We suspect the controller stopped working because the power was not cut off before wiring, which likely caused a short circuit. We previously asked you to record a video so we could accurately identify the issue, but you only provided photos. Pictures cannot show the actual operating status of the device and are not valid evidence to confirm a fault. After-sales support requires cooperation from both sides. We are unable to troubleshoot or arrange replacement parts based merely on descriptions and photos, and we hope you can understand. We believe you could spare a moment to take a short video showing the problem, just as you took the time to leave a review. If you are willing to send us the video, we will send you replacement parts free of charge and do our best to resolve the issue. We look forward to your cooperation.
The items work great. The customer support is great and responsive. The equipment comes in a predictable/consistent period of time for orders from China.
The product is smart and works perfectly. And if their is still a question: Easy & uncomplicated to reach out to 100G
The web site is very easy to use . You can find exactly what you want to buy . They custom built to your specifications. And what I like the most is you can easily buy extra batteries to extend the range of there ebike conversion kits
Excellent product with good communication from 100g after placing order plus fast replies to questions during installation and set-up. My only minor (very minor) negative comment relates to the inability to track the order until the package arrives in its destination country. Delivery estimate was accurate (about 4 weeks to the UK) but tracking only became active in the final two days which wasn’t very helpful and didn’t provide reassurance as to the progress of the package for the majority of its journey.
Hello! Thank you very much for your kind recognition and honest feedback. Our goods are shipped from China via a dedicated tax-inclusive logistics line, which operates differently from regular international courier services. The initial transportation is managed by our freight forwarder, and the shipping status is only available on their internal system. Please feel free to contact us anytime if you would like to know the delivery progress, and we will check it for you promptly. Tracking information will only be updated on the platform after the parcel arrives in the UK, goes through customs clearance and is taken over by the local delivery team. That’s why tracking details are usually available just a couple of days before delivery, and you will receive your package soon after the status updates. We have explained this logistics rule in the email sent shortly after your order, you may check it for reference. Thank you again for your understanding and support!
Really good, I recommend to use an handlebar remote. Front motor is better cause it doesn't interact directly with the transmission so you can go hard and add a lot of manual acceleration if you want that. edit : i have a problem with the kit everything working perfectly but just sometimes randomly or at specific location the kit wait to go under 20km/h to be able to kick back again and then work again perfectly as it supposed to do. I think it only happens in certain areas where the transition between downhill and uphill isn't sharp enough.
1. When the motor is installed, the bike becomes much heavier and much harder to pedal, when not using the battery. Pedaling becomes six times heavier and the quality of the bike drops to a very heavy and poor bike. This solution is good for people who want to pedal only with the battery and for a distance between 5 and 10 km. 2. As soon as you put the battery on, the battery level drops by about 20%. And when the battery reaches about 20%, the battery drains very quickly. According to my test, this battery has a capacity between 5 and 10 km, not 135 km as the seller has advertised. 3. If there is a problem, the buyer has no way to return the product. Even if you do not open the box and want to return the product, the seller charges about 40% of the amount the buyer has paid. I do not recommend these solutions. It would be better to buy solutions where the motor is removable. They are almost half the price. I don't recommend this seller either.
Hello, we have carefully read your review and would like to address your concerns accordingly. Firstly, regarding the riding resistance. After installing the motor hub, you may feel extra resistance compared with a regular bike. This is a common feature of all e-bike conversion kits. Our motor is built with an integrated one-way clutch and waterproof sealing rings. Such structural design will inevitably lead to slightly higher rolling resistance than ordinary hollow hubs, which is an inherent characteristic of e-assist motor kits rather than a product quality defect. The claim that the resistance has increased six times is just your personal feeling, not an objective test result. For a fair comparison, we suggest referring to other similar rear wheel conversion kits. Secondly, about the battery performance. Our batteries have passed strict quality inspections, and there is no issue of a 20% power drop immediately after installation. The battery level is calculated based on voltage, so the reading may be inaccurate occasionally, especially when the battery is low and vulnerable to voltage fluctuations. This is a normal display deviation, and the actual capacity of the battery is fully guaranteed. There is no video evidence to prove your statement about the short mileage. Actual range is affected by many factors such as riding mode and road conditions including steep slopes. Under normal use, the battery life is far longer than what you described. Lastly, on the return policy. We offer a 7-day no-reason return service for products that remain unmounted and unused. Customers only need to cover the shipping fees for delivery and return, and we never deduct 40% of the payment. We noticed that you had ridden more than 200 kilometers with the kit installed. Since the product has been put into actual use, we could not approve your return request, which is in line with our return rules. We value every customer's feedback and hope reviews can be based on objective facts. Wish you a pleasant ride!
Spokes broke multiple times, two time the mounting tray failed, once was because the plastic lock retainer cracked so the battery would not stay securely, I had to tie it with string. Bottle cap failed two times. And I had to find a purchase the correct glue and Drill to repair it. What if I didn’t know what I was doing? This could be dangerous. And for each time you sent replacements I had to pay for the delivery. Not happy with the service I received. And I wouldn’t recommend your kits because of it and that is a shame. As i work in the cycling industry and have many clients that always purchase what I purchase. You have lost a lot of referrals from me.
We have noticed you have had several after-sales issues with your kit, and we totally understand your dissatisfaction. We see the problems you mentioned happened for different reasons separately. The cracking of the mounting tray and bottle cap are very rare cases for us, and we are not sure if it is related to daily usage or riding conditions. As for the broken spokes happening twice within less than two months, this is also an uncommon situation. It may be related to long-term use on rough or complex road conditions. We always provide free replacement parts under our after-sales policy. For faults caused by different reasons, we charge a standard $20 shipping fee each time, which is reasonable and our regular policy. For the second broken spokes issue, we already waived the shipping fee for you, since it was the same type of problem. We are a responsible company and always try our best to support every customer and solve problems sincerely. There is no perfect product in the world, and we truly hope our thoughtful service can earn your understanding and trust.
