Early days yet. I will post more feed back with time.
My wife showed me that a thief who did not know how to fold a bike could take it if you were not looking, even if you were in a shop ect. I always presumed that I would hear the loud "clank" if someone flicked my Mezzo from half folded to folded. I conceded that I need to fully fold the bike and keep it with me, or lock it outside in busy area. However one of the great advantages is that I can take the bike inside local shops and half fold the bike. I therefore looked at remote bike alarms. Other threads have dismissed the idea of a bike alarm, but on a folding bike it could be just the ticket.
My search uncovered locks with alarms on and 3 cheap (?) far east versions on Ebay. So I bought the 3 cheap Ebay ones to try out
Honest remote. £18 including postage.
Works the best, but poor provided mounting system of stick on Velcro strips that is not secure enough. It gives off a moderately loud beep using the remote from several yards away. This feature is a bit of a pose, and possibly draws attention to a bike worth nicking. However it is possible to alarm the bike from a distance without returning to it .This is very useful if I get distracted, or spend longer away from the bike than I originally intended. I am happy with the alarm functionally, other than I wanted to mount it underneath my rack, but it is too large. The only secure way of mounting it has been to the forward racked unique Mezzo stem. See picture 2
The other remote system was about the same price. Runs on 3 AAA batteries. This is infra red and is direction sensitive to activate and disarm because of this. Its range is greatly reduced compared to the other remote version.This system makes it less usable on a folder due to the difficulty of knowing which direction the senser is facing when its folded! It has a cheap mounting bracket, but it does not lock in to place like a light. Blimey! But at least it has a mounting system. I can either tape it to the bike like I do the honest alarm, or use blue tack in the mounting rails ,or duck tape to secure it into a light bracket. Otherwise I could glue it permanent to a light bracket. It is not as long as the other version ,but it is still too wide to fit under the Mezzo rack. I prefer the above one so far to this ,but the mounting system makes this more moveable from bike to bike. Picture 1.
The other alarm was about £5 including postage. This is the neatest package, but functionally I am not sure. It has a wide clamp that can go around the seat post or the stem. I have put mine on my Mezzo stem facing forward. It has a combination type entry. It gives a bleep to tell you the mode it’s in. You just press the “B” button to set, and key in to code to disarm. One problem is that it seems to disable the keypad for a few seconds if you set it off having forgotten that it was set. Runs on a 9 volt battery. I may be able to adjust to this system in time. However I prefer to be able to remote setting it.Picture 3
So its abit like folding bikes generally. They are all better at different things. The quality of the two remote version is a bit suspect, waterproofing seem a bit of an after thought. The keypad version is the best quality, but it seems a bit of a fussy system, although its quick to set. I will continue to use at least the “honest” remote system for the time being.
Conclusion worth trying. It gives one confidence to go to the toilet, or counter in a café ,or to leave the bike while shopping.
We need someone like “Cateye” to make one that works well on a good bracket system with good long term reliability assurance. Let me know if it happens, its Christmas soon!
