Patented and built by Agentura Repro s.r.o. from the Czech Republic, GearSensor is an intelligent gear shift system for derailleur and internally geared hub bicycles using a mid-drive power unit, configured for 8FUN BBS01 and BBS02 conversion kits. 

GearSensor is the undisputed authority on design and development of this device which solves a common issue that all mid-drive (crank drive) electric bike drive systems are prone to. All electric bikes (whether a conversion or a factory production) utilise mostly standard drive train parts. These parts are designed to be used under the torque of a human, not in tandem to a powerful electric motor.

Whilst quality drive train parts are so well engineered that they are more than capable taking the additional continuous mechanical loads and impacts, there are issues for gear shifting. Both derailleur and internally geared hubs will have problems shifting between ratios under full power, especially for motor powers up to 750W (BBS02 750W peaks at over 1,200W).

These problems may be not very noticeable for the 250W units with a high quality derailleur gear set, but over time you will wear the parts from this undesirable shifting. Even though this may not be limiting the way you ride, GearSensor offers a great solution.

Agentura Repro has developed a GearSesnor for derailleur and internally geared transmissions (these are two different products) that senses shifting (up and down) and sends a signal to the BBS drive (usually though the brake cut-off input) that inhibits the power for the perfect amount of time required for a complete shift. The GearSensor works reliably on every shift so you don’t have to think about coming off the throttle or ‘blipping’ the e-brakes.

Use GearSensor with any 8FUN BBS unit conversion kit to get more out of your kit and to look after the gears on your bike.

Beautiful in appearance and quality
I've been using these for several months and I love them. They're sturdy and great quality, not to mention so beautiful. They do of course scratch up as you use your knife on them which is to be expected with wood but I plan to give them a little sanding soon and an oiling with the oil they provided. I would definitely recommend.

Ignore the bad reviews, read mine!
Pictures don’t make you think much, but in-person these are beautiful and well made. I’ve been trying to replace everything with cleaner safer alternatives. Honestly I love everything this brand offers and stands for! Some things to think about when you see other peoples negative reviews. Since these cutting boards are all around safe and clean with no toxic coating’s that most have to make them last longer, they do require more maintenance, when people don’t follow that maintenance you get a warped or cracked board. Also they are not meant to last as long as your plastic one from Walmart, they should be replaced more often. Luckily for a pack of 3, and I’ll say again that are TRULY non toxic, they are super reasonably priced! For what they offer I would even pay more for these. They do also come with instructions on how to care for them! So if you are the type of person to leave things dirty, or wet in the sink, these are probably not for you. For anyone who doesn’t mind taking the extra minute these are a must (literally a quick wipe, rinse and hand dry, it’s nothing). Gives me a breathe of fresh air to know I’m using safe, and clean products.

Cutting boards will splinter
A lot of the reviews that are saying these wooden boards splinter are true. I was excited to find some nontoxic wooden cutting boards for such a great price. Upon arrival, they seemed pretty decent quality when I pulled them out of the package. I proceeded to use the large one so I gave it a quick rinse with warm water and was taken back by fumes coming off the cutting board and then wiped it down with a white paper towel and my paper towel was brown. I was a little discouraged, but decided to give it a better rinse with a soap, free brush. At that point once I dried it off whatever coding was on it came off and it was rough and splinters everywhere. Definitely a little upset that the splinters could’ve ended up in our food. These are not good quality non-toxic cutting boards I would rather spend a little extra money on a quality board that is not going to sprinter Wood shavings into my food.

Very good, just be sure not to leave in water
Overall, this is a very good product as my wife and I are moving towards non-toxic kitchen materials. My only advice is to make sure to not leave this submerged in water otherwise mold will easily form.

Truly non-toxic but a little rough and uneven
I’m very impressed with the packaging of this. When I first opened the box I was shocked that there was a plastic wrapping around the boards when they promised to be non toxic but then I saw the sticker that the wrapping was not plastic and I was very happy. The boards themselves are pretty nice and a good thickness but the only thing is I feel like the board is a little rough and parts of the board come up and are not smooth.
