PRUNUS Bike Speedometer and Odometer Wireless Waterproof Bicycle Computer

I am very happy with this product. It is a very nice device for the price. and I'm very pleased with the instrument readings. It was easy to install and has been very accurate in its readings. I would buy this again. I recently had a problem with the unit after a battery change. I checked all the trouble shooting suggestions, nothing worked. I contacted Pronus explaining what was wrong. After some trouble shooting tips, the unit still was not responding accurately. Customer service sent me a new unit and now everything is back to normal and happy riding. . I definitely recommend doing business these people you will receive great customer service in them standing behind their product.

It started out working fine once set up. Now, it only works intermittently. I've changed batteries. Reset it and started over. It works for a few miles, then stops recording wheel revolutions, and shuts down. I'm one day over the return window, so I guess I'm stuck with it. Recommendation: Its a cumbersome unit to work with to begin with, and once it starts acting up, becomes an annoyance. Not buying it again, or should anyone else.

WORKS GREAT. What a deal for the price

It's great. Works great. Wireless. Works well on a bike stand (many wireless versions don't because the distance to the rear wheel is too far for them to handle. LARGE font!! 😉 BACKLIGHT ! Great Price ! You can manually sweet the Odometer reading. This is very good useful after changing the battery!! Many don't offer this option. Temp, Calories, Fat are bonus!! Downsides: (No cadence. But that is less important to me than backlight, large font, & wireless for rear wheel.) Requires *2* batteries. And they need to be replaced OFTEN! So stock up. WON'T EASILY SLIDE INTO ITS HOLDER, OR SLIDE OUT!!! Frustrating. It definitely takes minutes every time. And it winds up shooting out of my hands and on the floor several times while trying. FINALLY I added a piece of tape offer the battery life, because every time it landed on carrier, the back popped off. So I had to replace the battery, and enter the setup all over again. Didn't matter how tight I twisted the lid, it always popped off until o add tape. Most cycloputers will reset all the session stats at once. This one you have to select most of them individually. This can be a bonus, I suppose, of you want a running total for calories, say, but otherwise, it takes a bit longer to reset for each ride. And is more prone to error. The ORDER the stats are shown is a strange order that I just cannot get used to. Even years later. The "cycle thru" all starts is frustrating. Especially because of the order in which it's placed in the cycling thru display options. I usually don't like to use it, and is frustrating when I'm trying to reset stats, or set it to a particular start, only to find out that my stay won't reset, or to have the display unexpectedly change on me. I should get used to it by now. Maybe if it was in a different order I would? I do understand the usefulness of this feature for many people though. Location of turning the backlight in means I'm constantly turning it on when I don't intend to. Especially when trying to remove it or replace it into outs holder. So that doesn't help better life. I'm not sure where a better location would be tho, so I just try to keep an eye on it. it IS vet responsive. And better than having a 3rd physical button 😉 -- To be fair, this is the 2nd time I ordered this model. I have it on 2 bikes now, after the wire from my wired version on this bike broke. (I'd been frustrated over lack of backlight, and difficulty of reading its small font for years anyway. I already had this one in another bike, so for the price, I decided not to even try splicing that wire back together 🤣) Basically, I determined that a LARGE FONT & BACKLIGHT, as well as wireless (that works on a trainer) were very important features!! Usually I have on the backlight. But then spend the next several years frustrated at no backlight to read on a darkened room, PLUS a toil small font. Having backlight is far better than keeping phone or flashlight nearby. Because I almost always need it. So the quick battery usage, while adding quite a but to the price over time, and lack of cadence, and strange order of display wind up being less important. And the more labor intensive way of resetting the states. I've learned this the hard way, over years. And learned it again. Oh and how the location of the backlight means I often turn it on (or off) by accident. Usually On. All in all, I think the worst part of this device is that the manufacturing specs for the computer and it's holder are a miss. It WILL go in and CAN be removed, but it's an unreasonable exercise of frustration every time. The best parts are the size, backlight, and having a wireless version for mounting on a the rear wheel. At a reasonable price (even if you have to buy several batteries/year, instead of 1 every several years)

Great product, well worth the money. Bought this to use with a bike trainer stand i just purchased to track my exercise while my stationary bike parts come in. I didn't expect much out of this device, just wanted a general idea of my work out stats, but I am very impressed with its accuracy. Just going off of the info from my stationary bike (calories burned, time, speed & distance) that i was consistantly getting from months of use, i'd say this device is impressivly accurate. Another edge this product has over other brands is that is can be mounted to the back frame/tire, a necessity for me because my front tire does not spin in the trainer stand. I bought & returned another highly rated reader cuz it didn't have the range to collect info from the back tire. Only negative to this device is the sensor and magnet it uses to generate your info needs to be very close, like 3mm away which requires a lil bit of adjustment to get it to work, but the other device i returned had the same distance too, so i think that will be common flaw with any device. Also when mountiing the magnet make sure to put it on the outside of the spokes, closest to the tire. The closer it is to the center the faster and more inaccurate your speed/reading will be. But in general I am very happy with this product, price & shipping speed.

I said this up about three weeks ago do use on my recumbent bike, and when I took it out of the trunk yesterday to ride it had reset itself to zero. I was really disappointed because I was watching the miles accumulate. The instructions told me how to reestablish the miles, and after an hour of fiddling with it I was finally able to get most of the functions to work again. This is just really too difficult to set up other than from scratch. If you want to re-insert your numbers, it is a nightmare.

I bought this to replace a previously purchased computer that stopped working (not getting the signal from the sending unit after 1-2yrs of use). I followed the advertised rear wheel installation (only about 85cm or 65% the advertised allowed distance between the sending unit and computer). I checked that the sending unit and magnet were working with the receiver next to them before fully mounting things, but when my son went for a ride...nothing! Looked at the instructions again and they suggest that the computer back must face the sending unit to work; well how the heck is that supposed to work with one mounted on the rear wheel? So, I moved it to the front wheel and reduced the distance between the units to <50cm (<40% the advertised distance), and it still didn't work after the sending unit was mounted on the handlebars (magnet and sensor were still working when check during mounting of those parts). To conclude that the unit is not even worthy of the one star given (and inability to rate features), I moved the unit from the handlebars slowly closer and closer to the sending unit; viola it works ONLY when the distance between the parts is <30cm (12in). This is useless for even a 20" kids bike, let alone the adult size bikes it is advertised for. Would I recommend this unit? Absolutely NOT; in fact between this and the prior unit that died, I would not recommend any wireless computers/odometers.

After nearly 3 months, the right button just stopped working. Not a broken spring or anything, it just quit. I really love the big display and night light on this, so I'm giving it another shot. Maybe I bought a bad one- but for only $16 maybe I got what I deserve.

EXCELENTE PARA PODER COLOCAR EN RODADO TRASERO Y HACER RODILLO

Sigo batallando para programarla

No me he podido acomodar con el velocímetro solo pude usarlo una vez y de ahí no se que pasó ya no quiere funcionar o leer el sensor.

No sirve

No manda datos al ordenador, el vendedor nunca me contestó, lamentablemente se me pasó la fecha de devolución y ahí lo tengo sin funcionar
