Chronology
PredecessorE-Z Rider

The ENC E-Z Rider II (EZR2) is a line of

ENC, formerly ElDorado National–California, in Chino and Riverside, California starting from 2001. In addition to the different available lengths, the buses were sold with a variety of prime movers, ranging from conventional diesel and LNG/CNG combustion engines to diesel-electric hybrid and hydrogen fuel cell
with an electric traction motor.

As of 2015[update], a second restyling (the E-Z Rider II BRT, first introduced in 2008) is the sole model offered.

Design

ElDorado National (California) filed an application in 1994 to trademark the name E-Z Rider, and the cited date of first use is 1996;[6] The E-Z Rider was a 30' (nominal) bus with a 152-inch-long (3.86 m) wheelbase,[7] although LADOT used propane-fueled E-Z Riders with 139 in-long (3.53 m) wheelbases for the DASH service.[8]

The E-Z Rider II was introduced in 2001 to succeed the earlier model. A version with a restyled front end (E-Z Rider II MAX) was introduced in 2005 and sold alongside the original until the original was discontinued in 2007. A more visible front end restyle (E-Z Rider II BRT) was introduced in 2008, and the MAX was sold alongside the BRT until the MAX was discontinued in 2014; since 2015, the BRT is the sole model offered. The front and rear overhangs of the BRT measure 91.5 and 115 in (2.32 and 2.92 m), respectively.[9][10]

It is the first heavy-duty transit bus offered by ElDorado National, who was better known previously for offering shuttle buses for universities, airport hotels, small transit fleets, and car rental services.[11] Like most low-floor buses offered in North America, the E-Z Rider II has a partial low-floor layout, where the seating area from the rear axle to the back of the bus is on an elevated platform to provide space for the engine and transmission.[1] The CNG fueled variant is approximately 10% more expensive than the diesel.[12]

The Axess BRT model increased overall length from 40 ft 8 in (12.4 m)[13] to 41 ft 3 in (12.6 m),[14][15] increasing the front overhang from 94 to 100 in (2.4 to 2.5 m).[13][14]

Hybrid

Big Blue Bus #2903, EZR2 BRT with gasoline-electric hybrid drivetrain

LADOT contracted with

Capstone Turbines generated electricity for a Siemens traction motor and lead-acid battery.[16]

The E-Z Rider II was sold with hybrid electric propulsion, including at least two buses (to Big Blue Bus serving Santa Monica, California) with gasoline-electric hybrid powertrain systems integrated by ISE.[17]

The Axess is available with a hybrid drivetrain, at approximately a 50% premium compared to the cost of a bus with a conventional diesel engine.

parallel hybrid and series hybrid operation.[18][19]

Fuel cell

The ThunderPower prototype bus using a UTC Power hydrogen fuel cell and a 30' E-Z Rider II chassis was tested by SunLine Transit Agency in 2002, including three months of revenue service. ThunderPower, LLC, a joint venture of Thor Industries (the parent of ElDorado National at the time) and ISE Corporation (a hybrid drivetrain integrator), designed and built the ThunderPower prototype.[4] It was subsequently tested at Chula Vista Transit[20] and AC Transit.[21]

E-Z Rider II 30' bus chassis in the early 2000s.[4]

After completing the Axess BRT chassis for the first AFCB, ElDorado National delivered it to BAE Systems in New York, who integrated the hybrid drivetrain and fuel cell systems; the first AFCB was delivered to SunLine in November 2011 as fleet number FC3.[24]: 16–17  Revenue service at SunLine began in January 2012;[22] FC3 met "Buy America" certification for American-made component content.[25]

The fuel cell variant of the Axess uses an electric drivetrain that was developed by

hydrogen fuel cell, with additional power supplied by a lithium-ion storage battery capable of providing 200 kW of power and a capacity of 11.2 kW-hr. Up to 50 kg (110 lb) of gaseous hydrogen fuel can be stored on board, compressed to 350 bar (5,100 psi).[26] The electric traction motor has a continuous output rating of 215 hp (160 kW) and a peak output of 270 hp (200 kW).[27]

A second-generation fuel cell bus, now branded Axess-FC, was unveiled in 2019 with improved range.[28]

Deployment

125 Axess buses were shipped to airport facilities in California and Florida in 2004 and 2005. Some of the buses shipped to Fort Lauderdale–Hollywood International Airport had diesel-electric hybrid powertrains.[29]

AFCB operators

Before FC3 entered revenue service with SunLine Transit as the first fuel cell Axess, the E-Z Rider II-based ThunderVolt bus had been assigned SunLine Transit fleet number FC1 in 2002, and a subsequent

New Flyer Industries H40LFR-based bus (originally built for BC Transit) was assigned FC2.[30] SunLine received eight additional AFCBs with the same drivetrain as FC3 and improvements to the battery and fuel cell cooling systems[31]: 4–5  between 2014 and 2018, which were assigned fleet numbers FC4 through FC12 (skipping FC7).[32]: 10  FC7 was a variant of the Axess-based AFCB, built as a "battery dominant" bus with a lower fuel cell output.[33]

Unlike FC3, which had its powertrain and fuel cell installed in New York, the subsequent AFCBs were all assembled entirely at ElDorado National's Riverside, California factory.[31] By July 2018, ENC had produced 20 fuel cell buses for transit agencies throughout California,[34] including SunLine, UC Irvine (2015),[35] and OCTA (2016).[36] Also in 2018, the AFCB/Axess-FC was the first fuel cell bus to complete the heavy-duty transit bus (12-year/500,000 mi (800,000 km) lifecycle) testing at Altoona, Pennsylvania.[27][37]

In 2017, MBTA bus operations announced plans to test an AFCB/Axess;[38] an earlier MBTA fuel cell bus was designed in 2008 with a Nuvera/Fiat fuel cell and a BAE HybriDrive hybrid powertrain.[39]: 33
