Written Review

Full suspension mountain bikes are my favorite type of ebike because they deliver comfort and a “go anywhere” build that can work on the trails, mountainous terrain or just as well in the city. Sure, there are no fenders, no rack mounting points and no bottle cage… but I usually wear a backpack large enough to fit my laptop or some basic supplies and food. The thing about electric bikes is that they get you to your destination faster than traditional pedal power bicycles, thus encouraging more frequent and lengthy rides. The flip side of the coin is comfort, riding any bike for an hour or more can get a little uncomfortable and thus, fatter tires and full suspension takes its place. Don’t get me wrong, this is a fully capable off-road machine that would be great for dedicated trail riding or all mountain… even cross country if you stiffen up the rear shock. I love the remote lockout on the fork because it allows you to minimize bobbing on smooth terrain, really empowering you to pedal. And that’s also where the drive system shines.

Powering the BULLS SIX50 E FS 3 RSI is a Bosch drive system with upgraded high-torque CX motor. It spins super fast, is extremely responsive, packs in shift sensing and is very durable. My Uncle has been using an older version of this drive system on a full suspension bike for nearly two years now without any motor or battery issues. He added some fenders and a beam rack but often just wears a backpack. That’s the thing about this type of bike, it can be your transportation and your weekend fun! The increased drag of 2.25″ wide knobby tires and added weight of the 400 watt hour battery pack are easily overcome by the motor which should deliver upwards of 30 miles per charge… ~60 if you keep the assist level low. There’s no throttle but my experience with the system has been that the four levels of assist actually mean something with the lowest just overcoming the weight and drag of the bike and the highest feeling super responsive and powerful. You should be able to ascend nearly anything as long as you switch gears appropriately. In the video review above you can see me climbing some impressive sections off-road with constant speeds above 13 miles per hour, even reaching 17 and 18 at some points.

The drawbacks of the Bosch system is that it doesn’t blend in with the bike especially well. The bike stands out as being electric which might bother you riding off-road where others are getting around the old fashioned way. Bulls has done an excellent job integrating the motor and battery in my opinion, blending the colors and surrounding and sort of cupping the base of the battery with some extra metal flanges. I love that in addition to a chainring protector there’s a tensioner with narrow wide teeth to reduce kickback and chain slip. The tensioner is surrounded by a guide that might clear debris and also protect your clothing (if you’re commuting to work with pants for example). I like the four bar rear suspension as well, it orients the RockShox Monarch vertically keeping weight low but unfortunately also taking up the triangle space where a bottle cage might have tried to fit. The frame comes in three sizes for improved fit and since you’ve got quick release on both wheels and a super easy to remove battery and display this bike can be tossed onto most car racks or thrown into the trunk. It’s versatile, good looking and… kind of expensive. Given the Shimano hydraulic disc brakes, Deore XT 11 speed drivetrain and other upgrades like locking Ergon grips, Schwalbe tires and thru-axle design (front 15 mm and rear 12 mm) you’re opting into a higher end product. But, you get what you pay for and Bulls offers a solid two year comprehensive warranty with five on the frame. It’s an e-bike that’s built tough and fairly complete though I would love to have seen a seat post dropper. The seat tube is wide accommodating 30.9 mm posts so you could upgrade this yourself. I prefer the zippy feel and power of the Bosch system to the Brose and others, I really appreciate the shift sensing technology even if it does’t work flawlessly. The speed at which the motor starts and stops is very easy to work with and allows me to pedal more naturally at higher RPM. The motor does make a little bit of extra whining noise as demonstrated in the video but overall it’s great. Bulls did a nice job protecting it with an Aluminum scuff guard along the bottom that’s replaceable if you really push it to the limit. Big thanks to Bulls for partnering with me for this review.

Pros:

  • This is my favorite type of electric bike, having adjustable suspension front and rear significantly improves ride quality as you go further and at higher average speeds… both shocks are from RockShox and are light weight air designs, the front features remote lockout for easy positioning on cross country rides where the rear might be set stiff simulating a hardtail
  • The Bosch drive system is a proven winner that will last a long time and be serviced efficiently (through Magura in the US) if something goes wrong, batteries are easy to find and the system is forwards compatible with the new 500 watt hour battery pack
  • The combination of wheel speed, crank speed and pedal torque measurements delivers some of the fastest pedal assist response I’ve gotten to try and I love that there’s an integrated shift sensing system to reduce chain and sprocket damage (especially for an off-road bike like this)
  • The bike has a nice aesthetic, everything from the colors they chose to the motor integration and battery seat help to blend the bike with the electric systems
  • Excellent power delivery thanks to the Bosch CX motor which offers higher torque output of up to 75 Newton meters in the highest assist level
  • Both the battery pack and display panel can be removed from the bike easily, this is nice for transport, outdoor storage and if you’re riding on difficult terrain and are concerned about crashing the bike…
  • The 27.5″ wheel size has become popular for trail, all mountain and some enduro ride styles because it carries momentum and spans gaps in terrain while remaining maneuverable and relatively light weight
  • I love the enlarged rubber slap guard on the right chain stay, it should keep the entire length chip free despite the lower chain height and possibility of bounce given the off-road nature of the bike
  • Awesome tires from Schwalbe, the Rocket Ron model comes tubeless ready and has evolution liteskin which means thinner lighter weight sidewalls to reduce overall bike weight
  • Sturdy 15 mm thru axle on the front wheel improves strength and handling, I find that it also makes swapping wheels quicker and easier, especially with disc brakes because they line up easier, you get quick release in the front and rear for easy trail maintenance and transport
  • Large bash guard surrounding and protecting the sprocket, nice chain tensioner and guide just ahead with a surround design that will not allow it to come off track and might clear debris and mud reducing chain suck
  • Beautiful wire management (as with most Bosch electric bikes) the shifting and brake cables as well as electronic wires are all internally routed through the frame
  • Four bar suspension with vertical shock in the rear keeps weight low, limits kickback and performs well under heavy braking but can bob a little more
  • Slight rise in the handlebars and option to flip the stem for negative angle can help to protect the display in the event of a crash, I’ve seen this sort of design with some Haibike models as well
  • The Intuvia display is awesome because it’s large enough to read, backlit and uses a remote button pad so you can switch between assist levels without taking your hand off the left grip, there’s an integrated Micro USB port on the right side of the display for charging portable electronics and I like the range approximation in the menus

Cons:

  • Motor operation is louder than some of the other mid-drive systems I’ve tested from Bulls and Impulse in the past but response time is noticeably faster
  • Compared with some in-frame battery designs, the Bosch PowerPack stands out a bit more and could generate unwanted attention… however, it’s more convenient to access and tends to be less expensive to replace
  • Given the Shimano drivetrain and brakes, the premium grips, saddle, tires and suspension this bike ends up costing more… would be nice if it had a seat post dropper for the price (the diameter of the seat post is wider at 30.9 mm so at least it should fit droppers if you get one after market)
  • I’m not a huge fan of the cage style platform pedals because they don’t offer as much surface area and can get bent in at the end (as seen in the video and pictures), consider replacing with clip in designs or a solid platform like these Magnesium Wellgo pedals
  • No bottle cage bosses, that’s kind of to be expected given the battery replacement and full suspension design but some of the Brose powered Bulls models were able to add them due to the integrated battery design

Court-This is an awesome bike that I would consider buying for city/bike trail use. The battery is so powerful, but yet pretty light considering the size of the cells. The fluid response sounds better than some of the Bosch mid-drives. I understand that the Brose motor has a belt instead of gears meshed together. I also spoke to Barney at Bulls on the phone and he indicated that the frame sizes are available in 41cm which would fit me perfect. This is a candidate bike for me! Thanks for your awesome reviews.

For sure! Glad you enjoyed the review Bob… I like the Brose motor a lot, while I believe there are still some gears inside to change from high RPM to lower high-torque use, I think there’s a belt connector somewhere in there to reduce vibration and possibly keep it quieter. So far, having used the Specialized Turbo quite a bit (which I purchased earlier this year to get a more thorough feel for Brose) it has been great.

I was referring to Bulls Estream EVO 27.5. (FYI-The post comment button is not active). but yeah I was also looking at the specialized turbo as my 2nd choice due to the frame sizes and the very handy throttle control. My dealer indicated that the bike may be discontinued in mid 2017 according to the specialized rep. Does your bike have walk assist, or has it been deactivated? That is so lame that the US has to interfere with those small details due to liability issues. Great job Court! I dream about having a job like yours! Been into bikes my entire life!

BTW-The Cycleboard people are up and running. Hope to see you on that awesome looking vehicle as well!

The Bulls Six50 TR Street is one of the 2018 bikes that piques my interest the most. Full suspension with pannier mounting and fenders. First time I've seen the speed motor tilted up as they've been doing with the CX. Looks like a lot of potential to be a great commuter bike. Alas no Bulls dealers anywhere near me.

Hi all, I am trying to narrow down the choices for a solid commuter and would greatly appreciate any input.

We had the opportunity to test ride BULLS six50 e2 street and lacuba e45 side by side, and they are both fantastic rides. From a brief test ride in a suburb they seem more or less equivalent, and spec-wise they are also similar. Do any of you have a word to put in for either?

These two bikes feel premium, and go for around $4k. My next question is if anyone had the opportunity to test ride any bike with similar characteristics (28mph, suspension) in a slightly lower segment, say $2.5-$3k, and have an opinion on the marginal value of the last $1000 invested?

For the record my commute is ~10mi one way, a few hundred feet up and down, paved but not super smooth. I do it on road bike, but want to save some time, my knees, and not be sweaty every day. I am willing to invest in a good commute, but I am really curious about what those last $1000 buys.

Thanks!

Lacuba E45 has a much bigger battery (650 vs 500 on the E2 street).
I would recommend the E2 street. You could make it ~50lbs if you change the front forks. You could run 12V Supernova M99 lights and you could carry an extra 400 or 500 powerpacks.
You could also look at Trek Xm700+ https://www.trekbikes.com/us/en_US/bikes/electric-bikes/xm700/xm700/p/1982140-2018/?colorCode=black

I have a Bulls SIX50+ E FS 3 which has a Bosch Performance line CX. I've ridden the bike about 50 times for about 400 miles total (I ride about 4 times a week) since I bought it in June 2017. In the past three weeks the motor and display unit (Intuvia) has powered off on it's own while riding 4 different times. I press the power button and it powers back up after about a minute. No error code is displayed. Is there some trick to see if there is a hidden internal error code somewhere? Any help is appreciated, it's an hour drive one way to the dealer I bought it from.

I am looking to buy a bike for my college age son. 5'7" 135lb who will mainly be using around campus. I am looking at anything 1600-3000. Interested in the best quality for the money. He will want a rack and fenders but doesn't want the bike to scream E-bike

Have never purchased an E-bike before and just tested a Juiced Cross current S.

All right! I got the bicycle today!

I usually make my purchases online. After visiting several LBS in Seattle, they didn't seem to know much about their Stromer, Specialized and Trek e-bikes, which is very disconcerting since your spending several $k.

After stopping by Seattle Electric Bicycles, I met the owner, Stefan and his store staff. Stefan and the staff were extremely polite, knowledgeable and not pushy. I took a lot of their time w/ questions and test rides. After my experience there, I knew I was going to purchase my e-bike there and not online. They also happened to have a lot of great sales going on.

I decided on the Bulls Six50 E2 Street in 51 with a 20 cog (from 15) chainring upgraded on the front and a Body Float. The bike wasn't in stock and was special ordered.

The bicycle handles and rides great, especially with the Body Float. It's pretty zippy, even in the "tour mode", which is #2 of the 4 modes (eco, tour, sport, turbo). I'll have a better idea of the range later this week. As far as handling, it was great.

I'd strongly recommend anyone in the Seattle and surrounding areas check out Seattle Electric Bikes. They have really good selection of mid-drive and rear-drive bicycles.

I am a 5'5 male 160 lbs.

A 17" comfort frame ST2 would work well. The bike has massive range and power but it does have occasional electronic glitches. If there is a dealer willing to support you, you will immensely enjoy the bike.

Other options.

41cm BULLS Six50 E2 Street - $3800

45cm Trek Super Commuter - $4999 ( I can imagine the standover height could be an issue here but lots of dealers to test it out)

Specialized Turbo Vado - $4800 (small frame size)

Raleigh Redux IE - $3000 (small frame would work well)

Someone in Atlanta area got one from @Chandlee EBS at Electric Bike Specialists (http://www.electricbikespecialists.com/) and you can read about the experience here.

@Ravi Kempaiah thanks for the great input. I decided on the Six50 E2, special ordered at the LBS and ordered a bodyfloat seatpost. The Supernova looks awesome but will have to wait on that for now.

Thanks for the suggestion on changing the front chainring to a 20T, that's definitely do-able!

Great choice!
It was a mistake by BULLS that they left out the front chainring to be 15T (EU spec) while all other speed pedelecs have 20T or 22T.
The bike frame geometry is a very versatile one and I am sure you would enjoy this immensely.

@Ravi Kempaiah , I really enjoy your posts and videos. I'm looking at the Bulls Six50 e2 Street as a cheaper alternative commuter to the Dail-E Grinder. With your experience w/ the ST2 S and the Dail-e Grinder, what are your observations on the advantages and disadvantages of both?

Happy to share my experience:

ST2 or ST2-S

Having put 20,000+ miles on this platform and many other bikes, I am always impressed by the quiet, solid and smooth drive feeling of the ST2.
If your commute involves long stretches of roads, ST2 will excel at it. It shines in the 23-26mph cruise zone. The range is massive and if your roads are in fairly good condition, then you will be very pleased with the whole experience.
The downside is the weight. It's like driving a Escalade SUV. It has its own inertia but once you get over it, it works fine. It's not super agile like 45lbs bike. If your commute involves a lot of stop-go traffic, you will find the lighter bikes are better.

Dail-E Grinder or Six50 E street

The Dail-E is light, fast and packs a lot of good componentry. BULLS recently reduced the price points on all their bikes, so that's a bonus. The Dail-E is light and makes it perfect for stop-go traffic and you can carry it up 10 stairs without much worry.
The Six50 E2 is a very nice commuter but any Bosch system needs more rider involvement and proper shifting technique to get the most out of it. It will also make you a better cyclist (if you not one already).
With a 500Whr battery, you can easily get 30-35 miles of range.
The componentry is decent. You may want to change the chainring from 15T to 20T (helps in maintaining higher top speed) and change the lights to Supernova M99 (makes a lot of difference). The stock front lights are inadequate. But, the brakes are excellent. The wheels are great and have never heard of people breaking spokes that you hear on some cheaper hub motor bikes.
The forks are heavy but do basic job in mitigating the effect of road imperfections. But, other than that, I can't think of any major negatives.

Overall, they are all very good quality bikes. If you have a dealer willing to back you up, you have really nothing major to worry about.

@Ravi Kempaiah , I really enjoy your posts and videos. I'm looking at the Bulls Six50 e2 Street as a cheaper alternative commuter to the Dail-E Grinder. With your experience w/ the ST2 S and the Dail-e Grinder, what are your observations on the advantages and disadvantages of both?

I recently test rode a couple e-bikes.

The first was a Vado 5. It was nice, but my ass and wrists were sore after a short bumpy pavement ride. Suspension fork and seatpost may be a requirement.
I'd probably consider the Vado 6 w/ a bodyfloat .

I tested out some Bulls and Haibike, with suspension forks and a bodyfloat. They were all Bosche CX (20mph), but pretty impressive. I may be more inclined to look at the Bosche Speed.

I haven't seen any LBS w/ Ohm or iZip.

The LBS I went to was very nice and took the time to test ride and educate me, will post more info about them once I figure out which way to go.

One I'm looking at now is the Bulls E2 Street w/ a bodyfloat seatpost. This fits most of my requirements and is nice that I can use as a lite MTB for the 1% I am not using it for a commute.

Thanks .
I intended to use as transportation , commuter .
What would be a competitor to the Haibike , with a Bosch mid-drive ?
As a commuter, it makes more sense to get a 28 mph bike.

Some of the choices I'm looking at include the Magnum Peak, Bulls SIX50 1.5, Voltbike Enduro, and Juiced CrossCurrent S (but the wait may kill that one). Any opinions on these? Anything else I should consider?

Does the motor work?

Yes, the dealer loaned me the battery from their demo Six50 and everything worked OK during the test ride.

Yesterday when picking up a new Bulls Six50 E2 Street I was unable to set the bike into any assist modes, and the headlight wouldn't come on. The mechanic and I thought this was because the battery wasn't charged, so he loaned me the battery from their demo Six50 and everything worked OK during the test ride.

This morning, after a full 12 hour charge, the battery lights show full but the bike won't go into assist modes and the headlight doesn't come on. It's almost like the bike doesn't like that particular battery.

I tried calling the office in Lynwood CA (number found at http://www.whitepages.com/business/bulls-bikes-usa-lynwood-ca-2) and was told Tech Support is OOO until later today. Hoping that @BULLSBarney or @Adam@BULLSeBIKES is watching threads and can help, or someone on this forum can offer a suggestion.

I took the updated BULLS Six50+ for a ride today.

My initial thoughts:

Provides a certain level of cognitive ease. If your shifting techniques aren't sharp then the motor will compensate for it and the experience is quite enjoyable.
Dynamic assist is useful when climbing some steep technical sections and when you don't want to lose the momentum.
Loss of range. On my other Haibike (S Rx), I only use Tour mode and very rarely the sport mode. This gives me ~30 miles on a 400whr powerpack.
But on a eMTB with knobby tires, eMTB mode and 500whr powerpack, I only got 29miles. I rode mostly on single tracks and it was not hilly. I can attribute this to the higher consumption in eMTB mode.
Personally, I would not get this update. Simply because the system is exerting itself too much and sometimes I feel like I only need minimal assistance. It suits those who doesn't care about the range and prefer very sporty riding dynamics. Sadly, there is no option to revert back to the older firmware once you update it.

My experience with eMTB mode (version 1.7.0.0) was different on my BULLS Six50+ FS 3. I found the assist level was generally weaker than sport mode and it required me to use my legs more than before the update. I also liked startups on the steeps better, it was not as abrupt and had less wheel spin. Eco, tour and turbo modes are still there so there should be very little difference to those who don't use sport mode much. Since updating to eMTB mode I've only been on one 10.5 mile ride with some very steep sections and so far I haven't noticed an increase in battery consumption, I'll have a more informed opinion about eMTB range after I get a few more rides in.

I've had my Bulls SIX50+ E FS 3 about 3 weeks now and I've ridden it about 16 times for a total of 170 miles. I've been very happy with the ride and performance. Luckily for me the LBS notified me that the manufacturer notified him of the crank arm bolts coming loose. I checked them and they were very loose and I tightened them. About 4 rides later the left crank arm came off while I was riding and I was lucky to be sitting on the saddle when it came off. I was able to find the bolt and put back together. The LBS had said that he was waiting for a "Bulls" fix but I guess they haven't got back to him yet. I'm thinking of using blue loctite after I clean the threads, what do you think?

SR Suntour has a "corrective action" on the cranks depending on the Bulls bike model number and the model number of the crank arm. From Suntour:

"SR SUNTOUR has found that the cranks supplied on some BULLS E-Bike Models(See attachment for complete list) tend to loosen over time.
Re-tightening the crank only works for a short time then becomes loose again. SR SUNTOUR has therefore decided to have all crank arms and bolts
replaced."

I have a 2017 Bulls SIX50+ E FS 3 that I've ridden about 25 times for a total distance of approximately 250 miles. My 10.5 mile loop has a 22 degree grade for about mile and then has some shorter steeper climbs as well. Two days ago I had the firmware updated from 1.6.0.0 to 1.7.0.0 which gave me the new eMTB mode. I didn't like it at first but after a couple miles I liked it better than regular sport mode. It does reduce the number of pedal assist level changes and I was hoping they had fixed the surging problem when in a larger gear on the flats but they didn't. I've only been on one 10.5 mile ride with the new mode so haven't had a chance to determine the effect on range. Someone else reported that they saw an increase in battery consumption but I didn't see that on my first ride. I'll post again once I've ridden with the new mode a few more times.

EMTB Mode launched last week and we've been upgrading BOSCH CX models now with a lot of great feedback. I had a chance to try the EMTB mode on a ski resort a few weeks ago in France on some Moustache ebikes. Love it and this changes everything with how the Bosch system functions.

Your bike can be upgraded if you have the Walk Assist option enabled. Once you do upgrade though, Walk Assist goes away and there's no undoing the upgrade.

Look for more tweaks in the months ahead from Bosch.

My 2017 Bulls SIX50+ E FS 3 was updated to the new eMTB mode a couple days ago. Walk assist still works just fine, It was not disabled.

I think we're going to continue to see this in the US as the market grows. We try to keep a pretty good stock of bikes in our shop, but you can only do so much. Inventory is a challenge that manufacturers deal with as well. It's a big risk in this growing market.
