Unfortunately, as this is not a bike that we sell we have no specification for the bottom bracket type or size. However, Most electric bikes require at least a 128mm width bottom bracket due to the torque sensor that is mounted onto the crankset. In this instance I would recommend you take the bike to your local Halfords store where a member of staff can measure the bottom bracket and advise you further.

This is the wrong length for this bike, you require the 122.5mm bottom bracket, item 271445

Yes this will fit the Carrera Kraken.

For the Outrider the 118x68 BB would be a better fit, Item Code 271510 or Shimano's equivilent Item Code 680702.

The current X-Rated Mesh utilises a BMX style Bottom Bracket. These are available from your local Halfords store as a Special Order Part (288956). If you require any further advise or fitting services please visit your local store.

We would recommend taking your bike into your local Halfords store where they will be able to advise you further on parts for this bike.

The FS26 uses an offset chainset, therefore a 68x118 (271452) or 122 (271445) would provide you with a better chain line.

Due to the Viking Urban Trail not being a bike a Halfords own brand bike we do not have any technical specification for the Bottom Bracket. However, the 113mm bottom bracket is used regularly on Viking bikes. In this instance I would recommend that you take the bike to your local Halfords store where the crankset can be removed and the bottom bracket axle accurately measured.

This will depend on the chainset that you are currently using, however, the correct size for the standard chainset should be 68 x1 18mm, such as the VP-BC73 68 x 118 Square Taper Bottom Bracket (271452). Should you require any further information please go to your local Halfords store where a member of staff will be happy to help you further.

Yes, this should be a direct replacement for your orignal bottom bracket, the optimal chainline for your bike is between 50-55mm.
