Bulls Six50 Mountain Bike

Bulls Six50 eBike Performance at Chino Hills State Park


I had the opportunity to ride a Bulls Six50 E 1.5 during the holidays and I loved it! Chino Hills State Park in San Bernardino county is open to electric mountain bikes (eMTB), so I took to the trails with the Bulls hardtail coupled with a Bosch Performance CX motor. I will be reviewing the bike and its performance as well as trail conditions. Come along on my ride through CHSP!

It was a cool southern California morning and I couldn’t sleep the night prior as I was anxious to hop on this electric bike (ebike). Soon after I arrived at the South Ridge trailhead off of Rimcrest Drive, I warmed up and saddled up on the Bulls hardtail. I immediately had a smile on my face and could not shake it for the duration of the ride. This bike felt responsive and the wider tires gripped the hard-packed gravel at the start of my first climb. Before I continue, here is the top level view of the ebike I rode:

I started by going east on South Ridge trail and then heading west on Telegraph Canyon trail. This was a little boring to be honest, but only because it was three rolling hills and later a long stretch of relatively flat climbing. The condition of these trails were great, however. It was clear of rocks and basically a fire road with hard-packed dirt and gravel.

The Six50 was in its element. I had the fork locked out and my posture was comfortably upright for the climb. I had the motor engaged on ECO mode for the first 3-4 miles and it was enough to get my heart pumping while traveling at 12 mph.

Mile 5 comes along and the trail is starting to get steep. I hopped on Sycamore Trail heading north towards North Ridge trail. Here, the terrain turns into loose gravel with periods of sharp, hard rocks. I kicked the Bosch motor up to eMTB (Sport) mode so I wouldn’t slip on the loose gravel that had settled on top of the rocks. I made the climb to reach North Ridge trail at just over 1,600’.

This is where things start to get lively. North Ridge trail is full of short steep climbs and fast, wide-open trails on the way down towards Raptor Ridge. Before making my descent, I slammed my seat as far as it can go and unlocked the front fork to give me 120mm of necessary travel. Between each peak and valley I was able to hit 26 mph before I made it down to the first singletrack section. The grass was above my head so I was glad I was wearing a long sleeve shirt and gloves. The singletrack section before Raptor Ridge trail made me truly excited for the rest of this ride.

Raptor Ridge is where the Bulls Six50 e1.5 shined! There was a tough steep climb up to the 1,711’ peak before bombing down a singletrack that had shorter grass. I had to set the motor to Turbo for half a mile to get to the peak. The views up here were picturesque and I couldn’t imagine myself getting up here in such a short amount of time with my non-motorized mountain bike. This eMTB hardtail gave me the energy and confidence to take the singletrack down at a faster pace than I had previously taken it.

I knew that this bike was suitable for the trails, but I didn’t know it was going to perform so well. The Bosch Performance CX motor sipped on the battery pack and I had ⅗ of juice left after this 16.6 mile ride. I had climbed 3,069’ in an hour and a half and if I chose to, I could have ridden in Turbo mode the whole time. I was pleasantly surprised that this hardtail was able to handle the varying terrain and fast descents. I was confident that the Bulls Six50 e1.5 was going to hold up and even though it’s not as slack as other Bulls models, it handled well in tight corners and descents. This is an amazing trail bike and more than capable to handle fire roads and steep climbs. I give this experience a 7.5 out of 10. The 120 mm travel fork was enough to get up and down, but I’ll have to come back with an electric, full-suspension shred sled to compare this ebike. I also want to try another ebike that has air suspension, preferably a RockShox Pike or Fox Float 34.
