Maketheone Bluetooth Wireless Speaker, Portable Waterproof and Shockproof Outdoor Speaker with 3.5mm Aux MicroSD Input for Mountain Bike Bicycle Cycling Electric Scooter (Black)

I have this on my electric bike for riding to work it's loud enough I can hear the music when the traffic is fairly heavy. Makes the ride to work fun

I use this on my road bike on both short ang long rides. The rubber band is not sufficient to keep it still, it keeps on moving due to the vibration. I reinforced this by adding more elastic bands. It is more stable on my bIke with an aero handle bar. I have not tested it with the full volume on as that would be irresponsible and unsafe. I need to hear and be aware of other road users. It is loud enough to enjoy the music whilst riding. I mainly listen on bluetooth connection but also tested the micro sd with mp3 files. It makes riding more fun. The longest i used it for was 6 hours. One of these days i’ll try using it for 10 hours. It does not take long to fully charge it. It is light! The other end is exposed, if it rains the water would defo get in the speaker but I do not ride when it rains so that is fine with me. I rate this 4 * due to the rubber band not strong enough to keep it still. This would be a bigger issue on a mountain bike. Customer care/service is world class!

Brilliant peice of kit

I bought this back late October for my stepdad, and it worked great. Bluetooth connected fine, attached to the bike fine, and it was LOUD. Fast-forward to a few days ago, though, and it's broken. The USB port broke off and is now rattling around inside it, so it can't be charged at all. I don't see any way of fixing it, so it's now useless.

Really quite a nice little gadget that I use a lot to listen to the radio when on the bike... loud enough for back street cycling, on major roads the traffic noise wins...

Nice speaker but not loud enough over road noise to hear at times.

Is an okay wee little speaker. When I cycle unfortunately I have to cycle along a busy and narrow road that's why I rather have the speaker than earbuds. However, the quality is not that good if you have to put the volume high up in order to hear your music while lorries and cars continue passing me by. But it's okay. What I am impressed with is the battery life. It seems to last forever. It is a good value for the money.

Only used once so we will see how long it lasts but great sound from a small device
