  • A full suspension, Bosch powered, cross country style electric bike with efficient 29" wheels, it's available in three sizes for good fit and would feel taller and larger for riders with long legs but still fits some shorter riders given the angled top tube
  • Quick release for both wheels ads convenience for fixes and transporting the bike, I love the sturdy thru-axles which improve strength and make alignment easier, oversized tapered head tube also adds strength
  • RockShox air suspension is light and highly adjustable with rebound and lockout (remote lockout up front), the Shimano hydraulic disc brakes offer low-effort braking and the XT drivetrain is high quality and versatile but not overly complicated with 1x11 setup
  • Unique chain tensioner elevates the chain to reduce slap and clears mud, the narrow-wide tooth configuration reduces slip and an oversized chainring guard protects it, in thick mud the smaller sprocket may allow for chain suck, the geared motor is more audible at high power and RPM, newer brand that may not be available to test in as many locations

Written Review

BULLS jumped into the US market for 2016 introducing an impressive range of electric bikes including the TWENTY9 FS 3 RSI shown here (it’s a full suspension cross country ebike with 29″ tires). This model comes in three sizes and could be especially comfortable and fun for taller riders or those with longer legs. The larger wheels elevate the bike but also smooth out terrain, improve traction and carry momentum once they’re up to speed. They aren’t as nimble to steer as a 26″ or the newly popular 27.5″ but for cross country, they work very well. I was impressed with the 120 mm air suspension by Fox, love the rebound adjust and lockout features (remote lockout for the front) and am a fan of the sturdy thru-axles and quick release systems (for easy trail maintenance or transport). The display panel and battery are also removable which makes transporting or charging the bike easier and as with other Bosch powered electric bikes, they are both easy to use and very high quality. You get a two year warranty on the electronic systems and in my experience they age very well but might put a bit of extra strain on the drivetrain (being a mid-drive). Thankfully, Bosch has a software-driven shift sensing system that helps to ease power off, I tend to slow my cadence and ease off when shifting gears to minimize mashing and slipping. This bike is very similar to one that my Uncle has been riding for over two years now which also uses the Bosch system and it’s holding up very well for him.

Some features and design choices that set the Bulls Twenty9 FS apart from the competition in my mind include an aluminum cover for the base of the motor, a chain tensioner that might clear mud and reduce chain slap, narrow wide teeth on the tensioner that reduce slip, an oversized bash guard on the chainring and extra small 15 tooth chainring and 40 tooth large rear sprocket (which combine for efficient starts and climbing power for you and the motor). It’s a beautiful bike, one that’s fun to ride and easy to use. As with other Intuvia operated Bosch ebikes, turning the bike on and choosing from four levels of assist is quick and easy, you can keep your left hand on the grip and operate the display by using your thumb and the display itself is large enough to read in an upright position (and backlit for night use). You can see this e-bike in action on a trail as I rode with my friend Rick the other day in a vlog video here. He has loved the bike so far but only had it for a month and not been able to comment on some sensitive areas I’ve heard about from other riders (for all similar ebikes) about how the remote lockout works and whether the lever is in the way or too sensitive and the possibility of chain suck (where mud gets clogged in the front sprocket area and causes the chain to wrap around and seize the drivetrain). For most riding, the bike should perform very well and I noticed and appreciated the latest of Bosch’s motors called the CX which offers higher torque.


  • I love the extra tiny sprocket guide / chain tensioner (similar to Haibike’s Sprocket Equalizing System) because it probably helps to clear debris from the chain and lift it above the rear swing arm, it should reduce chain slap on the right chain stay and possibly chain slip as well given the narrow wide tooth pattern
  • Despite being relatively new in the US (at the time of this review in 2016 Bulls had only been here for one season) the company has been selling bikes internationally since 1994 with ebikes in 2007 and seems to have a good reputation
  • The Bosch CX motor is a higher torque design offering 75 Nm vs. 60 Nm with the older 2015 models, it’s perfectly suited to an off-road model like the Bulls Twentynine
  • Extra large 40 tooth climbing sprocket in the rear (11 gears total!) and a smaller 15 tooth chainring for efficient climbing and easier pedaling since the bikes are heavier ~50 lbs with the battery and reinforced frame
  • Available in three frame sizes so you can dial in fit, as a 29er you get more traction, rolling momentum and a higher frame position so this could be an excellent choice for taller riders
  • The motor seems well protected by an Aluminum skid plate (that is color matched and appears to be replaceable), I also like that there’s a cuff built around the base of the battery so it melds with the frame visually and possibly adds strength or protection, the extra long and thick rubber slap guard also helps with chain slap
  • Comes stock with Ergon locking grips! Name brand, very comfortable and solid to ride with… given the cross-country orientation of this bike with 120 mm travel I like that the grips aren’t too thick or wavy like the GP-1 models, I think the grips were a good choice, the end pieces extend forward a bit and might keep your hands from sliding off
  • The shocks are both nice, high quality air suspension from RockShox with rebound adjust and lockout… the front suspension fork has remote lockout so you can adjust on the fly (again, good for cross country where the trail might smooth out)
  • Quick release on both wheels, this is one of the advantages of a mid-drive system, the axles are both overbuilt with 15 mm thru-axle up front and 12 mm in the rear, improves strength and makes aligning the disc brakes easier
  • Solid 180 mm Hydraulic disc brakes from Shimano offer excellent stopping power and the tiny levers are easy to reach and use with just one or two fingers… what you’d expect for off-road use
  • The top tube is designed with a steep angle and is able to drop pretty low on the seat tube (where it is reinforced) and this lowers stand over height making it easier to mount and handle, the suspension design itself uses the 4 bar link that is pretty efficient (formerly patented by Specialized, now open in the US)
  • I love that the battery pack is removable but can be charged on or off the frame, it secures with a sturdy locking core and just looks great, if you took it off it seems like there would be enough room to hang the bike on some hitch style racks like this
  • The Bosch Intuvia display is awesome, large enough to read but easy to remove if you’re bombing a downhill section or parking the bike outside, I love the remote button pad that lets you select between assist levels and explore menus like range, odometer, max speed etc.
  • Awesome two year warranty on the electronics (battery and motor from Bosch) with a total of five years on the frame from Bulls, nice since they’re newer in the United States
  • I love how responsive the Bosch centerdrive motor is, it kicks in and cuts out extremely fast because it’s measuring pedal speed, rear wheel speed and your pedaling torque over 100 times per second and it even has shift sensing software to ease off and protect your chain and gears


  • I can’t say for sure but the extra large chainring bash guard could cause mud and debris to build up and cause chain suck (a common issue for Bosch powered ebikes that have super small ~15T chainrings), this probably won’t be an issue unless you ride off-road in thick mud
  • Not quite as light weight as some of the other full suspension Bosch powered ebikes I’ve tested like the XDURO Fullseven but that might be due in part to the larger tires and 29er wheel size and extra skid plate and moulding around the battery
  • I’ve been told by some riders that the remote lockout mechanism with a lever as used here can be annoying because it gets bumped and switches too easily to locked, I haven’t had that experience but my ride time has been limited
  • Being geared, the centerdrive motor does produce some electronic whirring noises which become more pronounced in the high levels of assist and especially when pedaling cadence speeds up
  • Even though I trust BULLS and they have been doing well internationally, being new to the USA this and other models may be difficult to see in person and test ride before purchase

The Swedish Bike Show in Stockholm this weekend wasnt much to write home about.

It was the big swedish retailers showing of their bikes and only some ebikes from standard brands like Scott, Merida, ecoRide, Wallerang, Crescent, Monark etc.

No smaller retailer with any for me more exciting and interesting brands where there like Bulls, R&M, Haibike, Stromer, Cube or Moustache.

I will go to Elovelo (ebike store in Stockholm) this week and test ride and compare R&M and Moustache.

The search continues!

Hello fellow Swedes!
So im in the same position as you are. Been researching for over a year now.
Me and my spouse have moved from the city to the more rural forests of Närke and we want to go more sustainable.
To replace the diselvan as much as possible is our goal.

I've been reading everything and watched so many reviews from different manufacturers and i can't really decide.

So this Saturday we went and bought a rawbike from "blocket" for 12k SEK. It's a class II moped, 750w, 48v 15.4 Ah. 25km/h topspeed but i unlocked it to 35km/h. It's for my spouse so she can go to the bus and home.
We have a hill that is 3.5km long and has an elevation of 150m. I have to take that one home after working 12h nightshift.

For myself i cant decide what to buy. I'd like an electric ATV but there is only kidsized ones available.

The models i have researched so far:
Haibike trekking 7.5 or 4.0 (dual battery)
R&M - all of them, but supercomuter with 2x500w is the one i think.
Bulls Evo street http://www.pro-e-bike.se/sv/elcyklar-emtb-ebike/marken/bulls-six50-evo-street.html
Scott Sub Tour 10
Butcher and bicycles cargobike

Radrhino fatbike 750w - the Eu model is not updated with the larger battery yet according to their website.

My requirements are Bosch CX and 500wh battery. I'd like a dual battery setup since i have 25km to the city and i want to make sure i can go home at max assist and speed if i need.
And yes i will buy a dongle for it if i get one.

I think there is not much that differs between these models. Motor and battery is key. The rest i "meh".

But then there is the Super soco moped with 2kw and 29Ah battery for 32k SEK with option for another battery.
With the new EU rules there is the speed bikes too. Elcykelguiden.se had an article about it and they mentioned this site:

2kw, 60v 18Ah and topspeed 60km/h for 23k and possible less if you are chosen as a testpilot. I sent an email yesterday.
I like fatbikes and have an Kona Wozo fatbike as my current MTB.

E-Bike or Moped or something in between... That is the question.

Have a 2016 FullSeven Xduro RC and it came with Rock Shox 120mm travel Recon solo air forks. They were OK, but nothing like the Pikes on my Bulls. Also liked the slacker 66 degree head angle on the Bulls as apposed to the 69 degrees on the RC. I found a great deal on a new 160mm travel Lyrik but wondered if installing the longer travel forks on the 120mm travel frame would mess up the geometry. Turns out it totally improved the handling far more than even hoped! Don't notice the higher BB (maybe 20mm), but it gave me about 1 degree slacker head angle and just makes the bike so much better for the rocky terrain I ride. Before the upgrade I preferred my Brose powered Bulls, but now with the new fork and the e-Mtb mode software upgrade it's a total toss up!

I'm wondering if the geometry of this series of Haibike frames are pretty much the same. A buddy has the same year Sduro AMT with 150mm front and rear suspension and it has a 68 head angle which is the same as I now have.

This can certainly do light off road given the 120mm travel.

i been looking hard at Rad products. i like the way they answer questions. I did ride an older model rad city and it was soooo nice. I also rode a BULLS EVO and that was really nice... different ride all together. I am checking used bikes now and shops that sell used. I think for noobs an accessible repair guy is key. I'm prolly going with the rad mini but its hard too make up my mind... i think carr--less folks with e-bikes are the new badass's in town

The belts are a great low maintenance feature found on several bikes. Riese & Muller is probably the largest ebike manufacturer to offer these on many of their models.

Bulls also have the 2017 Lacuba E8 that uses the Shimano Nexus / Belt set up which is great. https://shop-usa.scooteretti.com/products/bulls-lacuba-evo-e8

Once people know and hear about the benefits of going with a belt we should hopefully see more and more manufacturers producing models for the NA market. The issue, for now, is basically the price as many NA's are still very price sensitive vs many EU regions when it comes to how much they want to pay for their bikes.

But the long-term benefits of these products should actually cost the owner less to operate and certainly require less maintenance which can be very convenient for a lot of people.

Hey guys, today while visiting the Raleigh Electric headquarters in Southern California, I was able to check out the 2018 Tamland iE ebike, which uses the Original LCD-Display from Brose, with the Brose Drive TF (Fast) motor unit. This display is one of my favorites because it's fairly large and easy to read, removable for safe storage, and the mount has a full sized USB Type A (5 volt, 500 milliamp) port built in to charge or maintain your portable electronics. There are two parts to this display: the LCD unit and an independent button pad which can be mounted within reach of either grip. The video below goes into detail but does not explain how to set the clock or how to show range estimates... sorry, I welcome your input in the comments below!

Quick tips:

[*]The buttons on the LCD include: Power, Lights, and Menu.
[*]The buttons on the independent button pad include: Up, Menu, Down.
[*]To reset trip distance, average speed, max speed, hold Menu and Lights on the display unit
[*]To activate walk mode, arrow down to no assist (you may see a little triangle next to the speed readout), then hold the down arrow.
[*]To change units from miles to kilometers, turn the battery pack on first, then turn the display off, then hold the menu key and power button on the display. I had to do this one a few times, it seemed inconsistent, but it does work :)

Things I like about the display:

[*]It goes bright for a second when you press any of the buttons... then slowly dims.
[*]It's removable, so it won't get scratched or weather-worn over time if the bike is parked outside.
[*]There's a USB port in the base of the display
[*]This display doesn't require its own coin battery like the Yamah and Bosch Intuvia displays do
[*]I like how the battery will stay active for two hours once you press the power button, this allows you to turn the bike on and off just using the display. After two hours, the battery goes into deep sleep mode.
[*]The display does have a range estimate menu, which I did not go into on this video. You can navigate there by pressing the menu button and it will update automatically as you change assist settings (Cruise, Tour, Sport)

Things that might be improved about the display:

[*]It has more menus that some of the other displays and the manual was a little confusing, do we really need total trip time? It always said zero for my test bike...
[*]The slide design to fit the display onto the mount does not start at the very top, you have to almost put the display down near the middle, then slide for a shorter section to have it click, and this always confuses me.
[*]It seems like you have to manually power on the battery pack with Brose drive systems, which could require a reach down or back, it would be nice if you could activate the bike directly with the on/off switch on the display like most other high-end ebike systems
[*]The Brose battery pack often uses a magnetic Rosenberger charging port which has a little rubber plug... but there's no leash or connector for the plug, and that makes it very easy to misplace and lose.

As mentioned in the video above, I have attached photographs of the official Brose instruction manual below (sorry about the limited quality, I took photos and then cropped them manually with a bit of contrast tweaks to be readable). The http://www.brose-ebike.com/ seems to be short on information about this particular display and it seems like they may open design up to OEM manufacturers like Bulls, Specialized, and others to make custom displays. You can see this on the Specialized https://electricbikereview.com/specialized/turbo-vado-6-0/ (which has two display options, one is a touch screen) and the https://electricbikereview.com/specialized/turbo-levo-fsr-comp-6fattie/ (which just had three buttons and a Bluetooth smartphone app). This particular display panel is Brose branded and is their original layout (as far as I can tell).

Using the word "best" opens up a whole debate. It really boils down to personal preference and fit of the bike, and riding style. My original intention was to buy a Bulls bike, but a demo deal on a Haibike made the decision much easier for me.

When researching for my recent ebike purchase, I was putting Bulls in the same category as Stromers: European-made, very high-quality, and expensive. If it was in my price range, I would definitely have seriously considered.

I have never ridden or even seen one. But since Bulls was formed by a cooperative of bicycle dealers, it does not surprise me that they would know how to design good bikes. That said, I know there are other good bikes too. The question should really be, what is the best e-bike for you?

There aren't too many full suspension 29er's with the Bosch system. One is the http://www.bullsebikes.com/product/twenty9-e-fs-3-rsi/, you might want to check it out.

A lovely bike. But, unfortunately, not for for long-distance tours: no eyelets for rear panniers and but a single battery. A full suspension does not necessarily preclude a baggage rack.

These manufacturers must understand that not all long-distance bicycle tourists are willing to contend with ugly upright heavy glorified Dutch-type city bikes a self-respecting, design-conscious soul is sure to eschew.

In that respect Canyon has been doing really well in the last couple of years. Unfortunately, their commuter line bikes have no suspension, are not electric and still cost ca. €2.000. And are permanently sold out, as well.

Also, I think any aluminium frame over €400 / bike worth €1500 and up must have smooth welds.

chain is not skewed when using all 11 speeds?
I think it is skewed and heavy wear...
or use only 3 rear speed when chain straight (5-6-7)...
Can you show in another video look at chain when 1-st and 11 speed?

Dude, all you ever wanted to know is RIGHT HERE: www.electricbike-blog.com. This guy has all the answers. If you can read, you can build an ebike with his direction. Do it.

The only solution for us is custom home mounted mid drives like the BBS02 or BBSHD. These are far better than ANY ebike you could possibly commercially buy, and you can fit them on pretty much any bike. www.lunacycle.com. The entry point is also fractional compared to a full ebike, and you can swap back to regular if you want. It's awesome shredding past $10,000 STROMER ebikes on my $1000 (motor+battery) Trek 4300 mid drive swap and knowing I'm pumping out 1200 watts peak and the St2 is barely scratching 750 watts at most, 500 nominal. Make it yourself, it's really easy and you wont regret it, plus you'll know how to fix it and can swap out with new batteries lickety split.

+Clinton Baltazor It's a 23 inch frame. Had it for a year and already well over ten thousand miles on it. I commute to work and everywhere else by bike, and I live in Iowa where it's super hot in summer and lots of cold and snow in winter. I keep saying I will have to build my own, but who has the time and technical know-how. I'll just keep pedaling until the right fit comes along. Thanks for the feed back.

Bulls is a brand that was brought to life by the ZEG, a purchasing cooperative consisting of a little less than 1,000 distinct bike shops. While I can't say much about the product quality first hand, they do have a somewhat bad reputation in terms of quality (hence the competetive pricing). What I can very much say is that of the two distinct ZEG member shops I've been in personally, none was even close to being customer friendly.
I had a misaligned front chainring shifter on my (cheapskate) trekking pedelec, which led to the chain falling off and taking with it the pedal sensor. At the second ZEG shop I visited to ask for a replacement part, I was first ignored for about five minutes, and after that a sales guy came around, pointed at the bike (I agree it's cheap, but still), laughed, said that they'd certainly not have any parts, and then (I kid you not) called his colleague over to laugh with him at the bad quality of my pedelec.
Which is still working today, three years and several thousand miles later.
Point is, buy from a proper company, not from assholes.

Bulls may have been a third-rate manufacturer till recently. But things look very different now. Up until a couple of years ago, to Me Bulls was a bicycle for novice riders who couldn't tell Batavus, Gazelle or Hercules from Cannondale, Specialized and Trek. The snob in Me would scoff at Bulls riders. But in the recent years, Bulls (especially its electric segment) has become so good I fail to see how Cannondale is better (save for the Lefty fork and really good road bikes).

Looks really nice on video! Honestly I thought it was going to look terrible judging from the pictures on their web page, but I was totally wrong. They did a nice job putting their own style into a fs ebike.

I liked the gimbal camera shots while you were ridding. The bicycle tilting back and forth made it seem like your riding it somewhat.

Can u do a Q & A so people can ask u questions about bikes

2 years ago

Aren't these Bosch systems geared real low with the small front sprocket? Is it practical to use a Bosch system like a traditional bicycle (pedal power) with such a limited, low, gear range? Seems like these Bosch systems should come with a sticker that says "Geared for tight trail, down hill or up hill riding. Only use 100% pedal power when the battery dies."

Does the front sprocket move at a different rotational speed than the pedals?

the tuning box is the most important add on for any electric bike, the first thing you should buy

The front sprocket is small unlike Yamaha that uses normal sprockets. The Bosch however as internal gearing that makes the small sprocket work as a normal sprocket. My bike started with a 15t front now changed to 18t. It's a cube hardtail and can reach speeds on flat of 30+ mph with resistance left. I do however have a tuning box on the bike so the motor don't cut out.

Yeah, most of the full suspension models with Bosch start to climb in price. It's a solid bike and I bet we'll see equivalent stuff in 2017 for a bit less
