The 2015 Trek Lync 5 27-speed will go for about $1320; the Lync 3 9-speed will go for around $990. Trek calls the Lync a “dedicated, low-maintenance, tricked-out commuter bike.”

Let’s start by giving Trek some credit for finally producing an off-the-shelf bike with an integrated light system. These are not dynamo hub powered lights, but are instead powered by a lithium ion battery that is rechargeable by USB. It will be interesting to see the longevity of these batteries. 

In any event, when Edwin did his comprehensive post “Lights for the Rest of Us,” Trek was one of the big guys that was noticeably absent from the bikes with lights market. So, welcome aboard Trek.

I have minor criticisms of the Lync model. First, why don’t they come with integrated racks, like the apparently discontinued Trek Belleville.  And why can’t it be as stylish as the Belleville? And, as always, I’m not a fan of straight bars that only allow one hand position.

The bike media has greeted the Lync with enthusiasm, including this preview by the Bicycle Times.

    A bike that comes with lights… a start. But with so many proven models out there (or, um, over there, in Europe or Japan) of bikes that come with integrated dynamo lighting, it is too bad they tried to invent a wheel here.
    A little correction. The "Lync 5" is not a 5 speed, but a 27 speed and the Lync 3 is a 1×9… just for the record.

    Thanks for the heads up.

    It looks like there is minimalist a rear rack, though it only has low rails for panniers, not a top deck for other luggage.

    Thank you for this post! And Edwin and Joseph, you answered the questions I had in my head.

    Edwin: I'd like to think that someone at Trek read your article and realized the need for bikes with lights! I assume they went with batteries as a cheaper alternative to dynamo hubs. And thanks for the correction – the 5 has 27 gear combos and the 3 has 9. I will make the correction.

    Joseph: Based on the picture, I think you're right. For some reason it's not mentioned in the specs.

    Cuter: You're welcome!
