Thieves steal seven bikes from Block Bikes in St. Johns

Block Bikes owner Ben Helgren is on the lookout for seven bikes after being hit by thieves on Sunday night (3/10).

In a post on his Facebook page, Helgren said the theft happened after the shop celebrated its sixth anniversary over the weekend. “As a small local business, our margins aren’t as big as some of the other shops and this certainly makes a dent right as the season is starting,” he wrote.

The thieves grabbed seven, yet-to-be assembled Marin bikes from the shop’s storage trailer. Here are the models and sizes: Marin Muirwoods size XXL in Red/Gold/Green fade; Fairfax SC1 sizes XL and L in Black; Marin Four Corners sizes M and XL in Black; Marin Stinson ST7 size Med in Light Blue/tan.

Keep in mind the bikes hadn’t been built up yet, so it’s hard to know exactly how they’ll look when built — and it’s possible they might be resold as-is or for parts.


Helgren has filed a police report and has sent video footage of the theft to the police. All seven bikes have also been listed (with serial numbers) on

Please keep an eye out for these bikes. If you see one or know where they are, please contact the shop at (503) 819-6839 or You can also call PPB non-emergency at (503) 823-333 with tips or 911 if you see suspects in possession of the bikes.

It’s been 4 years since the bike theft summit. How have things changed?

So sorry to hear about this.

I live around the corner from Block Bikes, and take a lot of walks around St. Johns. I will for sure keep a keen eye out.

Lots of stolen property and dismantled bikes on Lindbergh’s Beach, Swan Island. There is a good place to start. A rather healthy homeless camp/chop shop operation seems to be operating without fear right out in the open.
