We went to the cities of Denmark to find out,

what do people think about a bike that has a PentaLock system?

I have never experienced such a unique locking system on a bike before and how easy I could use it was just beyond my expectations. It works super great and it is totally flawless.

The lock is impossible to notice because it looks just like a regular bike, however, the hassle is gone and that is just awesome. Really impressed with all the features, especially the tracking and all this together for such a price, I think it is just perfect combination of value for money.

I will totally consider buying this bike, because it removes all the annoying hassle and makes my daily activities much easier. And the fact I don’t need to use a normal key, but proximity key in my pocket or wallet is just enough is so efficient and great that makes me like this product even more.

I can already see how this would make my life so much easier. I always need to search for a key while holding all my bags, so this proximity key would be just super helpful in a lot of different situations.

I really like the product and the great thing is I can have my insurance on it as well. And the fact that this can be implemented on almost any bike model is just impressive. I also like the alarm sound system because it makes me feel safe about the bike even more.

Marcus N.

26, bike enthusiasts and developer

The best part of the concept is that if break the lock then you break the bike. This is a very important factor for me, because I believe this will keep the thieves away and my bike safe all the time. I also like that I can locate my bike if needed and be notified if something is happening to it. The battery life is just very impressive for all the features.
