5.0 out of 5 stars The Onforu SK03 Is the Perfect Bike Companion

2026-01-30    -Larry T. Ware

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.

Best speaker I have bought

2026-02-25    -Ahmed

I bought this speaker on a whim, and am really surprised and happy at how great it is. The sound quality is excellent and very clear. It charges really easily and quite fast, and with its phone charging cable and you can just stick it into a normal uSB charging port. The speaker is about the size of my palm and it has a very nice feel to it, it has a rubbery feel, a slightly hard rubber but flexible at the same time to be able to put a hook onto it. It also has an attachment to put onto a bike which is already preset and all you need to do is just a little not turning knob it seems to be really good kind of strong hard durable plastic. Also includes a small rubber piece in the actual circle for additional grip. You can take it off the bike case thing with a little difficulty but it makes me feel like it will be secure when I do put on my bike and a sound Range and quality is good. It is easy to use on your mobile phone or other kind of electronic devices. Grey happy with the purchase I may buy one for my brother as well.

4.0 out of 5 stars Decent little speaker!

2026-02-15    -Chris Quinlan

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.

5.0 out of 5 stars Impressive...

I've had this on my bike for 3 months. It sounds great, and the battery life is amazing.

5.0 out of 5 stars Loud and cute

2026-02-09    -Alisha Valentine

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.

3.0 out of 5 stars Best value for your money

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

Angenehme Überraschung

2026-02-02    -Pentagram Peter Pan

Da ich mir ein neues Fahrrad geholt habe und ich im Straßenverkehr Kopfhörer vermeiden wollte, musste ein entsprechender Lautsprecher her. Meine Ansprüche sind daher recht klein, schließlich brauche ich unterwegs keinen Hi-Fi-Sound. Darum habe ich preislich zu diesem Lautsprecher gegriffen. In den eigenen vier Wänden bin ich aber ganz klar ein Audio-Enthusiast, für den Klang enorm wichtig ist und der auch geschulte Ohren hat. Die positiven Rezensionen schienen für mich etwas zu euphorisch. Nun, nachdem ich den Bluetooth Speaker testen konnte, muss ich allerdings sagen: Für den Preis ist der Lautsprecher super. Der Klang ist, wenn die Box frontal zum Fahrer ausgerichtet wird, wirklich richtig gut. Die Höhen und Mitten sind für den Preis schön detailiert gezeichnet und insgesamt wird ein Klangbild aufgebaut, das sich in Anbetracht der kleinen Dimensionen und auch anhand des Preises sehen bzw. hören lassen kann. Auch die Bässe sind auf meiner Wellenlänge. Es wird ordentlich Druck gemacht, sodass der ganze Lautsprecher ordentlich vibriert, ohne, dass etwas verzerrt. Ohnehin übersteuert der Klang nur in den seltensten Fällen. Bisher habe ich Classic Rock (The Who, Dire Straits etc.), aber auch modernere Musik (Arctic Monkeys, Gorillaz, Wolfmother) damit getestet und ich bin wirklich angetan.Die Einrichtung stimmt auch positiv. Über Bluetooth ist der Lautsprecher fix mit dem Smartphone verbunden, Die Verbindung hat sich bisher als absolut stabil erwiesen. Witzig wird es, wenn man ein Gerät wie einen MP3-Player über das beigelegte Line-In-Kabel anschließt und die weibliche Stimme mit dickem, chinesischen Akzent den Audioeingang betitelt. Die Verarbeitung der Bluetooth-Box macht auch eine gute Figur. Durch die Gummi bzw. Silikonbeschichtung wirkt das Gerät stabil und sitzt auch sicher in der einfach zu installierenden Halterung. Wer eine Klingel am Fahrrad montieren kann, hat auch die Halterung in zwei Minuten festgeschraubt.Einzig die Seitenknöpfe gefallen mir nicht so, da diese sehr schwergängig zu drücken sind und während der Fahrt nicht immer zuverlässig zu erfühlen sind. Ansonsten kann ich nicht meckern und vergebe 4,5 Sterne für einen Bluetooth Lautsprecher zum kleinen Preis, der dafür beachtlichen Sound liefert.

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.

Superbe enceinte, très satisfait de mon achat

2026-03-01    -Thomas

Son de bonne qualité et très bonne autonomie (je la recharge toutes les 2 semaines en l'utilisant 1 heure par jour sans mettre le volume à fond).Montage facile et rapide sur le guidon, enceinte très facile à enlever et à remettre pour éviter de se la faire voler, elle tient très bien malgré les bosses.J'ai fait un trajet sous une forte pluie avec, elle est bien étanche, par contre je ne recommande pas de l'utiliser sous la pluie (la pluie recouvrant l'enceinte le son est "étouffé" et les basses font sauter les gouttes d'eau sur l'enceinte).Je ne pensais pas avoir un produit d'une telle qualité à ce tarif, excellent
