We have stuck with XT Di2 for the rear shifting. It works, everytime! If it aint broke, don’t fix it! And we have also stuck with the 11-42 cassette as it seems to keep the majority of people happy. The jumps on the XT cassette between gear ratios isn’t too crazy either so keeps you pedalling a pretty smooth cadence. Always keep your pedalling smooth! You’ll look like your doing the Moon Walk!
Braking has been a matter of discussion for us here in Copenhagen quite a lot. Making sure that a fully loaded eBullitt, complete with rider and human and tiny human cargo can stop quickly and safely has been a matter of priority for us. In light of that, we ended up putting Shimano Zee 4 piston brakes on the eBullitt E8000. These brakes are designed for downhill mountain bike racing and feature a 4 piston caliper, which essentially doubles the amount of brake pad contact on the disc brake rotor. This ensures that even in wet, grimy conditions you will be able to slow down incredibly effectively.
It might seem a little over the top to go into all these details, but components are something we spend a lot of time discussing and even more timetesting thoroughly . We ride these things daily and in most cases, as a worthy alternative to using cars. The Bullitt must perform impeccably every day and do so year year. Components must function flawlessly and be simultaneously very durable.
