BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews

We have read all expert and user reviews on the Altor SAF. In summary, this is what cyclists think.

8 reasons to buy

  • With an 80 mm outer shackle, testers took more than an hour to cut through the Altor SAF. It exhausted multiple angle grinders, multiple blades, and multiple batteries in the process.
  • Both sides of the shackle lock into the crossbar, requiring thieves to cut it twice.
  • With an uncommon ‘disc detainer’ lock mechanism, an expert lockpicker says the SAF is unlikely to be picked.
  • The SAF is covered in a “cushion” coating, to protect your bike’s frame.
  • Owners report the SAF does fit around standard parking meter poles.
  • The SAF comes with 4x ‘disc detainer’ keys.
  • Despite its “ludicrous” size, the SAF does fit in a pannier.
  • Many users believe the burly looks of the Altor SAF can scare off thieves.

4 reasons not to buy

  • At 3.2” thick, 9.5” wide, and 13.7 lb, the Altor SAF is huge, heavy, and not very portable.
  • Users say the 3.2” shackle is too large to fit between most standard bike spokes.
  • With its wide shackle and moderate internal width, owners have limited options for attaching the SAF to their bike frame and lock points.
  • One tester claims to be able to “easily” break the SAF, using a 12-volt drill.

Bottom line

Altor’s SAF is designed to resist the efforts of portable angle grinders. This cartoonishly beefy lock is shod with an 80 mm outer shackle made of semi-hollow aluminum, in addition to a beefy 14 mm internal steel shackle (wider than the ABUS Granit XPlus 540). This can take multiple blades, multiple batteries and over an hour to break through. When it comes to the SAF’s bulk, e-bike owners are less bothered than pedal-powered riders. This lock is intended for riders who can leave it in place, to tie up their bike in the same location every day.

The Best Bike Lock

The Strongest Bike Lock

By effectively nullifying angle grinder attacks it deserves it’s place in this list. I must stress: the SAF is absolutely massive. This is not a portable U-lock. And neither is it a U-lock that offers lots of flexible locking options.

Watch Us Cut This “Angle Grinder-Proof” Bike Lock

What was that? 6 batteries, 4 blades, 2 angle grinders, a lot of sweat on me and probably a lot of attention drawn to this lock. That was 1 hr 10 mins of cutting. An unbeatable theft deterrent.

MASSIVE Altor SAF (“Strong as F***”) Bike U-Lock Picked

Because the tool required to open this is so uncommon, I can tell you the chances of this being picked on the street are essentially zero.

What's Inside?

What’s inside the UNCUTTABLE Lock?

It’s all it’s cracked up to be. That’s how you steal a bike. You cut the frame off, because the uncuttable bike lock is too massive. Either way that’s too much work.

Altor SAF Bike Lock (Drilled in Seconds)

Today we’re going to be calling out Altor locks. This thing can be bypassed with just a 12V drill, even though it has this big obnoxious aluminum shackle, so don’t worry about burning your grinder. It’s nothing special, just a brass lock.
