Written Review

Bulls created something special with their SIX50 E 1.5. This is an affordable, trail capable, city capable, electric bike offered in four sizes, running top-of-the-line Bosch drive systems. For just over $3k you’re getting a bike that looks good, is sold through a wide network of dealers globally (in the US since late 2015), and should last for years. Compared with other similarly priced models like the IZIP E3 Peak+, this e-ebike offers bottle cage bosses and fender bosses but has a higher stand-over height. Both bikes have thru-axles with quick release for easy trail maintenance or transport… but the SIX50 E 1.5 comes with a 25% larger Bosch Powerpack 500. The styling on this bike is good with an angled downtube that compliments the bulge of the battery pack and blends smoothly into the the motor casing. Note the Aluminum alloy skid plate mounted beneath the motor for protection. I was really impressed with the 50.5 lb weight of the medium size frame I tested for the video review above. That’s a good weight considering this has a coil fork vs. air, is running the larger battery pack size, and has plus sized tires with Boost (elongated) axles. As someone who loves commuting through urban environments on mountain bike frames (because of the comfortable tires and shock absorbers), I could see this ebike working great as a daily ride and weekend toy. And it would definitely handle both environments, this is more of a mountain bike that was specced slightly down to mid-level vs. a cheap urban bike that looks like it could handle trails. To set it up right, I’d grab a disc brake compatible rear rack, lightweight bottle cage, and possibly some small mud guards.

Driving the bike is a Bosch Performance Line CX mid-motor. This thing is rated at 250 watts nominal but tops out above 500 watts and is capable of a peak 73 Newton meters of torque. It’s compact, super fast, and one of the smartest motors around. The motor controller measures rear wheel speed, pedal cadence, and pedal torque one thousand times per second, and it even listens for shifting to reduce drivetrain wear. It’s the same motor used on ultra high-end full suspension mountain bikes and I hear from shops and customers that it is one of the most reliable. Admittedly, I’m a Bosch fanboy because they were one of the first systems to arrive in the US that delivered the kind of power and efficiency I was craving for true mountain biking. It might actually be a little overkill on this bike, if you use it mostly for city commuting and light smooth trails, but it’s good to know that it’s so capable. Note that the motor does produce a bit of whirring noise at high RPM but that it is capable of up to 120 RPM while some other systems peak out around 100. This allows it to assist you up to the maximum speed of 20 mph in a wider range of gears, not just the highest gear. The chainring chosen for the Bulls SIX50 E 1.5 has 15 teeth vs. 18 on the comparable IZIP mentioned earlier but they both use a 10-speed Shimano Deore drivetrain. What this means is that the Bulls is going to be a more capable climber and fit the 20 mph range better. The chainring on Bosch powered e-bikes spins at 2.5 revolutions per crank arm revolution so you can multiply the teeth to get a comparable traditional chainring size (38 tooth in this case). There’s a small metal chainring guard to keep pants and other debris clear and this might also act as a guide to keep the chain from coming all the way off if it bounces free.

Powering the bike is a high capacity Bosch Powerpack 500 with 36 volts and 13.4 amp hours of capacity. It’s impressive to see this pack on a bike that is priced so low because you get 25% more capacity in the same form factor as the older Powerpack 400 and the energy dense cells used for it are in high demand. The battery mounts from the top down and can be charged on or off the frame. Make sure it’s clicked securely in place before riding because sometimes the mounts are a bit tight when they are brand new. There’s a handle at the top for easier carrying and an LED power indicator on the left side. If you’ve got the battery stored separately from the bike, to reduce exposure to extreme temperatures or just for safe keeping, I recommend topping it off every couple of months if you haven’t used it. The battery can be stored comfortably at about half-full (which is how it ships) and should be very easy to find and replace for years to come because it’s so standardized… but you may not be able to find the same sticker pattern so consider keeping that if your old pack wears completely out. Expect upwards of 1,000 full charge cycles and years of use from this pack. The charger that ships with the SIX50 E 1.5 is a faster 4 Amp model that manages to stay fairly compact and lightweight at roughly 1.7 lbs. You can buy additional chargers (including a smaller 2 Amp version) from your dealer and this could be useful to store at the office if you’re commuting.

To power up the bike, just charge and mount the battery, then press the power button near the lower left corner of the display. The screen flashes to life very quickly showing your speed, battery level, and assist level in monochrome. It’s backlit with a faint blue that isn’t super distracting but also isn’t controllable. You can have lights wired into the system by some shops and this is handy because the display has a lights on/off button and integrated lights are just easier to work with than click-on independent models, in my opinion. Again, this is most relevant to people who might want to use the bike as a commuting platform. Look for Supernova lights that are made with sturdy alloy housings that can withstand trail use. A good example of these lights in action is the Riese & Müller Delite electric bike. Anyway, the display panel is easy to interact with by using the i button either on the Intuvia LCD or the remote button pad mounted near the left grip. I love how close the buttons are and how the center i button is rubberized while the up and down arrows on this remote pad are smooth and clicky. They become second nature very quickly and that’s key if you’re riding in traffic or a dynamic trail and don’t want to look down. And with the Bosch CX motor system, you can have the firmware updated to change Sport mode to eMTB mode which acts more like a torque sensor with the full range of power. Basically, it gives you all four levels in one mode, perfect for those conditions where you don’t want to be distracted looking down or clicking around. The display is a real highlight on this and other Bosch powered electric bicycles for me. I like how large it is, that you can swivel it to reduce glare, and that it’s removable and replaceable or even swappable with the COBI smart system that uses your phone as a display panel and includes integrated lights with turn signals. The COBI system is sold separately but was designed to just click into the Intuvia mount.

There’s so much to say about this electric bike because it’s so versatile. Maybe $3k doesn’t sound affordable to you, but just one year ago it was difficult to find any Bosch powered electric bike for under $4k in the US, and it wouldn’t have had the high-capacity 500 watt-hour battery or the high-performance CX motor. Bulls offers a wide range of models and I feel that some look nicer or have great features like full suspension or the clean integrated Brose battery vs. the stuck-on Bosch Powerpack, but they all cost a lot more. This is the kind of e-bike that you could buy and keep, ride around and bang up, expect to last for many years, and really use. The top tube is a bit higher with that traditional diamond layout and the resulting higher seat tube might make adding a seat post suspension uncomfortable if you’ve got a shorter inseam length compared to the IZIP E3 Peak Plus I keep referencing. Both models are interesting to me because of what they offer and the wide audience that could enjoy it. You do get suspension lockout here and a strong pair of 180 mm hydraulic disc brakes. The Schwalbe Smart Sam tires have active line puncture protection to reduce flats and the PSI range is a bit higher than the IZIP which combines with the slightly narrower tires for a more efficient ride. Big thanks to Bulls for partnering with me on this post and inviting me out to their headquarters in Southern California to do some back-to-back tests and reviews. I’m glad that they and other European companies are entering the US and delivering some high quality products.

Pros:

  • I love that even though this ebike is trail worthy, it has rear rack, fender, and bottle cage bosses! It’s a perfect platform for weekend mountain biking and weekly commuting around the city all rolled up into one
  • I think Bulls had the urban/trail commuting use-case in mind when they specced the ergonomic grips and low-rise handlebar, they hand position feels great and the grips reduce tingling in your hands for longer or more repetitive rides
  • At $3,099 this is one of the most affordable BULLS electric bikes and preserves the styling, warranty, wide dealer network, and quality that the company is known for
  • You get four frame sizes to choose from! That’s incredible at this price, and it’s important given the diamond frame (high-step) because the top tube is fairly high
  • A 120 mm spring suspension and plus sized tires offer comfort and traction, I’d consider adding a 30.9 mm seat post suspension like the Thudbuster ST for an even smoother ride
  • Stiff thru-axles on both wheels with longer Boost thru-axles, this provides stronger bracing angle for the spokes and accommodates the plus sized tires
  • Considering this ebike is using a spring suspension, I’m very impressed with the 50.5 lb weight, spring suspensions require less maintenance and tend to be very responsive
  • Diamond frames tend to be stiff and strong without additional metal (and weight), I like that you can lift them easily and carry them on hang-style racks
  • Beautifully integrated mid-motor and battery pack, notice how the frame tubing cups the base of the battery and helps it blend into the frame
  • The Bosch CX motor offers high torque and can be updated to eMTB mode which changes Sport into a wide range “do everything” setting that works more like a pure torque sensor, it’s perfect for off-road when you don’t want to fiddle with power level
  • Solid mid-level Shimano Deore drivetrain with 10 speeds to work with, this is enough for climbing and exceeding the top electric-assisted 20 mph speed
  • Responsive hydraulic disc brakes with large 180 mm rotors and adjustable reach levers, great for trail riding and the levers are nice if you get the smaller frame and have smaller hands or ride with thick gloves
  • I love that you get the latest Bosch Powerpack 500 with this bike, especially considering the price point, this pack offers 25% higher capacity than the standard Bosch Powerpack 400 but is backward compatible with that pack if you happen to already own one
  • The motor controller measures pedal cadence, pedal torque, and rear wheel speed 1,000x per second and feels very natural, it also listens for when you shift gears and tries to ease off power to reduce wear on the chain, sprockets, and derailleur
  • The motor is angled up and built into the downtube and seat tube area of the bike, this raises clearance, Bulls chose minimal casing to keep the bike looking sleek but did add an alloy skid plate along the bottom for protection against rocks and other obstacles
  • I love how the battery pack and display can be easily removed for safe storage or charging, this is a big deal if you commute with the bike and have to park outside at a public rack
  • The Bosch Intuvia display panel has a Micro USB port built in that sends 5 Volts at 500 milliamps so you could maintain a phone or charge other portable electronics while riding, this is great if you use your phone for GPS
  • This and most other Bosch powered electric bikes have walk mode which allows the bike to push itself forward slowly, this is especially useful if you have a rack loaded with gear in the city or are pushing up a steep hill in the mountains (like a technical section that you decided to walk)

Cons:

  • While the Bosch Performance Line motors are super responsive, they do produce a bit of hum or whining noise when used in the highest levels of assist or operating at high RPM
  • Many of the Bosch powered electric bikes stand out as being electric because the battery is connected to the frame vs. being slotted inside of it, but this makes removing and charging the pack easier and the standardized configuration makes it easier to replace
  • Plus sized tires tend to be a little heavier but the 2.6 is a good compromise (lighter than 2.8 or 3.0), you could always run them tubeless, still, they will add some drag and produce some buzzing noise on pavement
  • If you do plan to use this as a commuting platform, make sure you lock both wheels and the saddle because the quick release systems make them easier to steal
  • Sometimes when the Bosch battery packs are new, they require additional effort to click into place, just make sure it’s secure before riding off to avoid damage, shops can loosen or tighten the interface which is designed to reduce rattling
  • The pedals are a bit basic, I would consider replacing them with something with a wider platform and adjustable pins if you plan to ride trails or all-mountain, these Magnesium Wellgo pedals are a good option
  • The alloy bash guard on the chainring seems like it’s spaced out pretty far from the actual chainring, I haven’t noticed chain drops being an issue with Bosch? Perhaps this extra clearance reduces chain suck in muddy conditions?

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

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!

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.

I test rode a couple more and I ended up ordering a Bulls Six50 through a LBS.

I'll receive it sometime next week and I'll write up my experiences. Thanks everyone for the great input!

@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.

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 love the responsiveness and also actually the sound of the performance line motors when they accelerate. I've never tried anything but the Bosch performance line that is on my Cube. Once you get to know it you can really "feel" it, from standing still or balancing you can control it with so small movements of the pedals.
From this and your other videos I gather that the competitors don't offer quite the same experience in terms of control and response? I also wanted to ask, do you feel any difference between the earlier 60 Nm Bosch motors and the new 75 Nm ones in terms of the above?

well actually i guess it was talking to you when it told you to shift. You responded accordingly and then said something fascinating about it sensing your cadence- not to suggest you are e-doping your ride but it just suggests a kind of collaborative conversation - at least to me :-D
