Santa Cruz Blt 4 C MX 27 90 CH e-bike Matte Carbon is a full-suspension enduro e-MTB built for mountain biking with a focus on steep descents. It uses a Bosch mid-drive motor and a mullet wheel setup for stability up front and agility at the rear. It’s a performance-class bike aimed at riders who choose components and geometry based on the terrain.
The foundation is a Carbon C composite frame with 170 mm of rear travel and a mixed-wheels design. The geometry features a Flip Chip Hi/Lo adjustment that changes the bottom bracket position and head angle. The head tube angle is 63.6° in Hi and 63.3° in Lo. Sizes S through XXL have a reach of 435–525 mm and chainstay length of 440–452 mm.
Drivetrain: SRAM 90 Eagle T-Type shifter and derailleur offer 12 speeds and Single Click mode. The SRAM XS 1275 Eagle T-Type cassette has a 10–52 tooth range, and the crankset uses a Bosch ISIS BB.
Brakes: SRAM Maven Base hydraulic disc brakes are designed for enduro loads and long descents. SRAM HS2 rotors measure 200 mm front and rear.
Wheels and tires: The wheelset is built around Reserve 30|HD AL rims and DT Swiss 370 hubs. Up front is a 29" wheel with a Maxxis Assegai 2.5" tire, and in the rear a 27.5" wheel with a Maxxis Minion DHRII 2.5".
Cockpit: OneUp Aluminum Bar handlebars have a 35 mm clamp diameter and 800 mm width. The SDG Tellis Dropper seatpost offers 125–230 mm of travel depending on size, and the saddle is an SDG Bel-Air V3.
The mullet setup adds composure to the front wheel on rough descents and speeds up direction changes thanks to the smaller rear wheel. The slack head angle and long reach support stability at high speed and on steep sections. Fox 38 up front and Float X in the rear match enduro travel needs, where traction and support on landings both matter. The Bosch Performance Line CX Gen 5 motor keeps the pace on long climbs and helps maintain cadence in technical terrain.
This bike is for experienced riders who link enduro trails, natural descents, and technical climbs in a single loop. It’s also a good fit for riders who want downhill-like geometry but with assistance on the way up. Compared to lighter trail e-bikes, it’s aimed at higher loads in rough terrain and longer descents.
