    • Worth it
Color: Black
I mounted this speaker to my ebike. It has excellent sound and only used 10% of it's battery after 1.5 hours of travel. The instructions are complete and easy to understand. The mount is marginal.

    • The Onforu SK03 Is the Perfect Bike Companion

This is a wonderful product; very good quality, bright, clear sound, with plenty of undistorted volume. It attaches snuggly and securely to my old 10-speed's handlebars and stays in place when encountering jarring bumps on the trail. Also, there is no skipping of the audio when in micro SD card mode during rides. The audio is crystal clear even at high volumes. The battery has plenty of life and the speaker is simple and easy to use. I purchased the Onforu SK03 speaker to replace a name brand bluetooth speaker that I paid 3 times as much for 1 year ago. What I like about the Onforu is the ability is play directly from a micro SD card. This eliminates having to charge and manage a both a speaker and an MP3 player. You can navigate forward or backward from song to song on the micro SD card by using the + and - volume buttons. A longer press on the buttons increases or decreased the volume. The Onforu has more volume than my old one so classical pieces with quiet passages will now be heard while riding. The four buttons have double functions making the Onforu very convenient and versatile to use. I would highly recommend reading through the supplied owners manual to understand how all the features work. It can switch manually between SD, Bluetooth, and Aux using a short press on the power button to jog between them. Or it will automatically connect to the correct mode upon power up, depending on what is hooked up at the time. If an SD card is inserted it will power up to the SD mode. If nothing is connected it defaults to Bluetooth mode. If something is plugged into the Aux jack it powers up on that mode. (The manual clearly states how this all works.) This model has a 3.5mm aux jack and supplied cable so it can be used with older MP3 players that are not Bluetooth. The speaker sounds as good as the old name brand speaker it replaced - only the Onforu has much more volume. One of the things that impressed me as I was reading some of the negative feedback on this product was how willing the company was to correct problems. Mine came without the set screw that tightens the bracket to the bike handlebars. I contacted the supplier (Onforu) and they quickly resolved the issue by refunding some of the purchase price - more than enough to cover the cost of a new screw. They responded to me within 24 hours and placed a refund through Amazon the very next day. I'm very impressed. I would have no reservations about purchasing another one of these amazing speakers. ... show more

    • Functions great and the perfect size
Color: Black
This is a great Bluetooth speaker! It is loud and projects sound so well my son puts it on his scooter and scoots along jamming to his music. It is clear and we are very please with it. We also use it in the house and it has been a great Bluetooth speaker for the price. It is the perfect size! Would purchase again. ... show more

    • Decent little speaker!
Color: Blue
Serves its purpose! You won’t confuse it for some fancy audiophile equipment, but it works, it’s loud enough, and it’s a safer, low-cost alternative to riding with headphones.

    • Loud and cute
Color: Black
Loud speaker and easy use even while riding! Got this as a gift for my son to put on his e-bike and it’s amazing! Way louder than i expected for the size. It’s just small enough to not protrude but packs a great sound. He can hit the skip button on the volume button while he’s ridding and it’ll skip to next song on his playlist. Easy to charge the battery on it and battery lasts for hours! Even on full blast the clarity isn’t sacrificed and we can enjoy music while we ride. What a cute speaker to listen to music while we ride. ... show more

    • Great Sound!

I’m very pleased with the sound quality. I like to listen to Cubs games and audiobooks while riding. The sound is clear and not distorted. Music sounds good also. I bought the blue speaker and the blue matches the blue on my Lectric e-bike.

Best value for your money, holder for it isn't the best, ending up using a clip to keep it on. Good quality sounds and the battery last for a long time
