I wear a Helite Turtle 2 mechanical hi viz yellow vest. I've had it two years now, and feel like I can rely more on the mechanical than the electronics presently. This was two years ago at Meteor Crater in Winslow, Az.

Zitat von azqkr im Beitrag #3 Agreed, I have a 'mechanical' one and have no inclination whatsoever to swap it for an e-version. Electronics to go wrong, and batteries to charge. Have a look at Fortnine (YouTube: https://youtu.be/N2jZryt607U) on the subject. I'm certainly a big fan of the technology: the paramedics who loaded me into the ambulance a couple of years ago reckoned my Turtle had saved me from serious injury; probably a broken neck judging by the damage to my shoulder and helmet...

So would someone care to explain the difference between the two systems? Fairly obviously there has to be a sensor on both determining that there has been an RTA. Why on earth rely on a bluetooth or whatever connection to transmit that information? Is the sensor on the bike rather than on the waistcoat? If that is so I do see some sense. I hate things that tie me to the bike but equally I am very familiar with poor bluetooth connections . 19 Plate R1250RS Exclusive with "bells & whistles" & full colour matched luggage |

Zitat von PlacidoD im Beitrag #5 Yeah agree about the layer thing; personally it's probably the single biggest disadvantage to wearing it - although there are big gaps under the arms and in front it does stop what might otherwise a welcome blast of cooling air when riding in Europe midsummer. Still doable though. The other issue for me is when I get to my destination I'm stuck with this large, bulky, unfoldable object to wear or lug around round with me off the bike (it includes a back protector). Doesn't fit in a topcase like a helmet. I've been known to lock it to the bike using a cable lock through an arm hole. As for the price - meh. I'd be feeing pretty stupid right now sitting in my wheelchair counting up how much money I'd saved by not buying one... especially having chosen to ride something as exhorbitantly expensive as a BMW!!

I have worn an Alpinestars TechAir 5 since its release last August. It is worn under your jacket and incorporates a standard CE1 back protector. My experience is very positive. The vest fits great and is a perfect match for wearing under my AeroStitch and textile jackets. After the vest is activated, I don't think about it at all. It doesn't interfere with riding at all. Activation is easy, although the status lights are by your waist which makes checking status more difficult than it needs to be. All the sensors are contained within the vest...no GPS or Bluetooth connections are required for use. There is an app, which is terrible, for updating the vest firmware. Battery life is claimed to be 30 hours, and that seems about right in my experience. Charging is by USB. |

I am inclined to stick with low tech. I think I will stick with Turtle 2 and tether myself to the bike.

I have the tethered (non-e) Turtle. |
|
Zitat von Biscuits im Beitrag #9 Depends on how much slack you leave in the tether. When I stood on the pegs with the GS, the tether obviously had to be longer to accommodate. Now on the RS, I don't stand on the pegs and have shortened the tether. The mind is the limiting factor |

Zitat von azqkr im Beitrag #10 Hmnn! I fairly regularly ride non-stop for circa four hours just standing on the pegs for a minute or so when riding at low speed e.g. through a town to take the weight off my backside. I suppose there is nothing to stop me having two tethers on one bike (or adjust the length before setting out for that occasional long run). Certainly with two bikes I can have a shorter tether on my commuter machine. It should not be beyond the wit of man to invent a simple quick release means of lengthening the tether to permit standing on the pegs and then a single twist and lock or whatever to take the slack out of the tether when back in the saddle? P.S. I have looked carefully at the E-Turtle for the above reason but at the moment it only seems available in the UK via import from France with a base price of around £650 to which VAT and import duty and carriage would have to be added. So likely £800 or more. And then there is an extra £200 or so for the optional fork connector (or in my case likely £400 for two bikes)!

Zitat von azqkr im Beitrag #10 The e-Turtle will always trigger faster in a frontal crash, even if you make the tether short enough that it is almost no slack. If you crash into something, the fork sensor on the e-Turtle is going to trigger before your body moves relative to the bike to pull the cord on the mechanical version. The difference may not be much, but it could trigger 20cm earlier on in the crash even with a taught cord. That 20cm could be a lot in a frontal crash. Remember that the inflation time is 0.1s on top of the triggering time; that's a chunk of time in a crash. I spent a lot of time looking at slow motion frontal crash tests (with crash test dummies) to reach this conclusion. Given the additional complexity of a e-vest, I'm still happy with a mechanical vest though. |

I think I have a solution to standing on the pegs - a 2nd tether with a large carabiner on the end mounted on the nearside and the normal tether set to allow standing on the pegs on the off side. Taking the slack out via the carabiner would effectively mount the tether centrally. I have loads of webbing around the house plus a few carabiners so easy enough to give it a try.

Zitat von Bunter im Beitrag #14 A colleague has ridden on track wearing a Helite GP-Air which appears to be the tethered version from the picture he sent at the time.. I can ask tomorrow.
