are they by any chance related?

this is common with what are essentially generic Chinese bikes.....

Although they look the same and may have the same basis, they are differently specified and the £695 Kudos model is a better buy than the £645 Proteam.

The Proteam from general retailers with unknown support extent only has a li-ion manganese battery type. Kudos are an e-bike company that supports it's products and it's model has a much longer lived LiFePO4 battery. These more than justify the small price difference.
