Kryptonite Evolution Mini-7
The lock to buy if the bike is genuinely at risk. A 13mm shackle in a deliberately small U, because the less air inside the lock, the less room a thief has to get a tool in — that is the whole design argument for a mini.
Who it is for: City parking, or anywhere the bike is left for hours.
- Why it lands.
- A thick hardened shackle in a deliberately small U, from a manufacturer that publishes an honest security rating instead of the words 'heavy duty'. It is the lock for a bike left in a city for hours, and it costs enough that commuters keep meaning to buy it and do not.
- Who it suits.
- Anyone who locks up in a town or city, at a station, or anywhere the bike is out of sight for the working day.
- Check first.
- Where the bike is left. If it is a quiet suburban workplace with ten-minute stops, this is heavier than they need and the cheaper Parkview on our new-cyclist page does the job. Nothing to fit - it comes with a frame bracket and a cable for the front wheel.
What is good
- 13mm hardened shackle, near the top of Kryptonite's consumer range
- Small shackle opening leaves no leverage space for a jack or bar
- Includes a 4ft cable so the front wheel is covered too
- High on Kryptonite's published security scale, which is a comparable number
What you give up
- The small U is genuinely hard to get around some racks and posts
- Heavy — you feel this in a jersey pocket or a small bag
- Roughly four times the price of the Parkview
Skip this if. Skip this if you mostly stop for ten minutes at a time in quiet places. The weight and the awkward small shackle are a daily cost you pay for a risk you are not carrying.
