The Monster E S is a hardtail, mid-drive, Bosch controlled, fat-tire ebike from BULLS. At $4,899, it is less expensive than the full suspension form, yet at the same time really advanced and premium contrasted with most fat-tire bicycles out there. For fat-tire bicycles these days, usually to see a center engine, throttle, and some section level parts tossed on for good measure. The Monster E S then again is utilizing the highest point of the line Bosch Performance CX mid-drive engine, has pressure driven brakes, and uses a RockShox front suspension. The bicycle comes is aluminum composite and comes in 2 outline sizes (46cm and 51cm).
Bulls Monster E S Electric Bike Review
Just 1 shading here, however I do like the green and white accents and there is a ton of dark on dark shading coordinating all through, so by and large, an extraordinary look. The hardtail is decent here since it brings the expense down from the E FS adaptation and it additionally has rack supervisors. No bumper managers here anyway from what I can tell, however I guess you could discover a seat post mounting one. That inflexible seat post is 30.9mm so you could include a suspension situate post on the off chance that you felt it was inadequate in solace. I think the solace is still quite great here, particularly from the 26" x 4" Schwalbe Jumbo Jim fat-tires. They are evaluated for 5-30psi which is an extraordinary range. I want to bring it down right to 5psi for sand or snow, it truly sparkles here. Notwithstanding, do be cautious with the lower psi as it makes free elastic overlays that can cause squeeze pads AKA 'wind chomps'. I cherish that they have these magnificent square gap punched out edges with dark tire liner, they diminish weight a great deal, make some give, and add to that open to feeling as well. 15mm dividing through hub in the front and a 12mm separated 9mm hub in the back, both with fast discharge. Aiding more solace is the RockShox Bluto RL Solo air stun. It has about 100mm of movement, has a remote lockout, and is truly lightweight. By and large, the setup is 52lbs, which isn't awful for a fat-tire with suspension. Different things I see here are an unmistakable plastic sticker slap monitor, decreased headtube, and non-bolting level elastic grasps.

Driving this electric bike is a trail advanced mid-engine from Bosch called the Performance Line CX. It's evaluated up to 75 newton meters, impressively more than the standard Performance Line and Performance Line Speed, which crest at 63nm. Given the somewhat heavier impression of this bicycle, it's an extraordinary decision. It most likely blows up the value a bit, however you do profit by an uncommon eMTB drive mode that just the Bosch CX offers. In this mode, which is the third step up just before Turbo, the engine execution can work from 120% to 300% dependent on how hard you push. Different modes (Eco, Tour, and Turbo) have progressively constrained power groups. This drive mode was acquainted as a route with make engine execution increasingly programmed and natural for mountain bikers who may concentrate on trail deterrents and apparatus moving. For the Monster E S, which has too smooth Shimano moving and is intended for trail riding, eMTB mode is only one all the more way that the bicycle can be ridden without diversion or thought. Simply bounce on, bolt up to eMTB, begin accelerating, and the bicycle will react normally dependent on how hard you pedal. All present age Bosch Performance Line engines weigh generally 8.8lbs, which is more than Shimano, Yamaha, or Brose drive units. The CX delivers more clamor, particularly in high power and a higher pedal rates, and it likewise utilizes more vitality… however it's known for being solid and having a decent system of affirmed fix shops. This engine reacts dependent on three signs: back wheel speed, pedal rhythm, and pedal torque. It utilizes the absolute most developed sensors and can even detect when gears are being moved. Precisely, the bicycle the bicycle is worked by a 11 speed, 11-40 tooth tape by means of Shimano Deore XT with a shadow in addition to grip. The Shimano setup has shifters going 2 high and 4 low. For brakes you get these Magura MT5 180mm rotor water driven brakes, extremely a choice decision for halting this brute. All things considered, there is a great deal of fun in the manner it rides, it is exceptionally spotless, quick, and lithe.

Driving the engine and illuminated showcase board, is a 482.4watt hour battery pack from Bosch. The battery, a PowerPack 500, ticks perfectly into the downtube. It may not be as spotless as the more current PowerTube Bosch batteries, yet I am upbeat they ran with it here. It is lighter weight and is good with swapping out some other Bosch PowerPack batteries. You can charge the pack off of the bicycle casing or attachment into the port when mounted on the bicycle, be that as it may, it is close to the wrench arm so do be cautious. Lithium-particle cells, including the 18650 cells utilized in this pack, will in general be truly dependable on the off chance that you keep up them at 20% to 80% limit when not being used and store in a cool dry condition versus outrageous warmth or cold. I much of the time store my electric bicycle inside in light of the fact that it isn't as substantial or rotten as a sulked or cruiser, and this guards it clean and keeping in mind that additionally shielding the battery from extraordinary temperatures. Charging happens rapidly here, gratitude to the included 4amp Bosch charger, yet it's moderately minimized and lightweight contrasted with others available. Bosch sells a much littler, lighter charger, that conveys 2 amps. They call this the movement charger and I read numerous remarks from individuals who use it at a work site or convey it along in a knapsack or pannier. All things considered, the PowerPack weighs not exactly the PowerTube at 5.7lbs versus 6.3lbs, yet you'll need to ensure to hear it fit properly on the edge when mounting before rides. On the off chance that you have a more established PowerPack 400, it will work with a similar interface as the PowerPack 500, so you can swap packs or lease and obtain in the event that you travel regularly.

When you've charged and verified the battery pack, working the bicycle is really straight forward. The control board comprises of a grayscale LCD with four encompassing catches. The power catch is incorporated with the top edge, a + and – catch is reachable along the left front bit, and a walk mode catch is incorporated with the lower edge. Squeezing the power catch breathes life into the LCD rapidly, and a black out white shine is dynamic consistently making it coherent in low lighting conditions. I've made an inside and out manual for the Bosch Purion show board, with video diagram, in the EBR gatherings. It's not removable be that as it may, and the Micro-USB port on the correct edge isn't dynamic for charging similar to the case with the bigger Bosch Intuvia. I very much want the Intuvia for its size and extra menus (move proposal, clock, max speed, normal speed, and excursion time), and a few shops can overhaul you to this presentation for ~$200. With Purion, you have a streamlined and basic interface with the necessities including trip remove, all out separation, and range gauge. You can burn through these menus by holding the – key, and you can reset trip separate by holding – and + at the same time for two or three seconds. The primary bit of the showcase is utilized to demonstrate your present speed and help level. On the off chance that you'd like to change units from miles to kilometers, you essentially hold – and tap the power catch. Whenever you change starting with one help level then onto the next, the menu quickly changes. As far as I can tell, the catches don't click in as reliable as Intuvia, and there's no devoted light catch (hold + to actuate the lights on the off chance that you have the CX engine), yet it takes care of business. In the event that this was the main showcase that Bosch created, I may be somewhat more energetic about it here, it is an incredible presentation, I think I've quite recently developed to welcome the charging, removability, shading, and Bluetooth includes on a portion of their more pleasant presentations. The greater part of the mountain models I audit here do spec Purion, to cover up and ensure the showcase. For me, it would have been worth an extra $50 or $100 in the sticker price given how costly the bicycle as of now is, however it is anything but an arrangement executioner using any and all means.

Taking everything into account, the bicycle is a ton of fun and the more premium setup truly sparkles. On the off chance that you get an opportunity to see the audit video, look at it, I adored how responsive the framework was the point at which I took it on some shoreline rocks, it was great! In any case, the Monster E S has a few tradeoffs. There was no incorporated lights here or a Monkey Link setup like a portion of different BULLS bicycles, so that was somewhat of a bummer. I likewise saw no locking grasps and no jug confine managers. What's more, I ought to likewise specify the Performance Line CX is a very noteworthy engine, however it creates more clamor and just as some drag on the off chance that you are taking it to the maximum or are riding with the electric framework off. All things considered however, BULLS is an incredible organization that offers a seller arrange, exhaustive guarantee, and brilliant help. They utilize a great deal of astounding segments and it truly appears in this bicycle. I truly had a huge amount of fun and I am energized I found the opportunity to look at this one, so a major thank you to BULLS.

As usual, I welcome inquiries and input in the remark segment underneath. Regardless of whether you possess a past rendition of the bicycle, have stepped through an exam ride, or are fresh out of the box new to the space, I will likely give a goal and legitimate asset. You can likewise join the BULLS Ebike gatherings and offer your own photographs, recordings, and survey updates to help other people! Have some good times out there, and ride safe :)


An increasingly premium fat tire bicycle with suspension, it utilizes a standout amongst the best engine and battery frameworks accessible, Bosch CX with the PowerPack 500, and is accessible in two sizes for improved fit and ride comfort

The engine is extremely responsive and directly there for you quickly, I was inspired how it dealt with the sandy rocks I got the chance to take it on in the video, particularly an able machine

Schwalbe influences premium tires and these ones to can be changed over to tubeless to spare weight and keep running at lower weight, I adore that the edges are punched out for weight funds and give

Premium drivetrain with eleven apparatuses, a single direction hold to keep the chain tight on harsh territory, a composite chainring defender and solid combination manage with thin wide sprocket so you ought to never battle with drops, chain slip, or chain suck (which can some of the time occur in sloppy conditions on the restrictive littler Bosch chainrings)

Trail-prepared 100mm travel air suspension from RockShox Bluto with remote lockout, dark anodized covering on the stanchions gives quality and improves sliding

The engine is situated for most extreme ground leeway yet additionally has a composite slide plate underneath for included security on the off chance that you have a stone strike

Both the engine and battery pack are situated low and focus on the edge, this improves taking care of, decreases unsprung weight contrasted with center point engines, and I feel that BULLS has worked superbly mixing the two things into the tubing structure of the casing so they look great

The cockpit is spotless and strong, you get the reduced Bosch Purion show board, and there's a lot of space for the triggers

The two wheels offer brisk discharge, which consolidates with the removable battery to make this bicycle lighter and simpler to transport, I generally take the battery off when stacking onto bicycle racks

The Powerpack 500 offers a great deal of limit in a minimal, excessively lightweight bundle, the mount for this battery is in reverse good with the more established Powerpack 400 battery in the event that you have one, I like that the two packs have a coordinated handle and can be discovered worldwide for simpler leasing or substitution

This Bosch charger is one lightest and quickest models around, offering 4 Amp yield and weighing simply 1.7 lbs, it doesn't require any dongles to associate and charge the battery off or on the bicycle

The Bosch CX engine offers a ton of zip and torque, up to 75 Nm with almost 570 watt max, it's a standout amongst the most solid mid-drive frameworks around and now includes an eMTB mode with variable power yield dependent on pedal torque… so you can disregard the help setting and spotlight on changing gears and directing, this is especially valuable on delicate landscape

It's decent that Bulls planned this casing with a more extreme top cylinder to bring down remain over stature in light of the fact that occasionally in the event that you hop off into sand or snow, your feet could sink and you may rack yourself on a higher cylinder

Hardtail doesn't constantly mean less, with this edge, they included back rack supervisors, so you could truly stack this thing up for an end of the week experience

Through pivot on the front wheel for greatest solidness and quality, decreased head tube is likewise more grounded and works with more pleasant forks like the Bluto here

The battery lock center is made by ABUS and accompanies a code card so you can buy locks "scratched alike" and have less keys drifting around causing perplexity

Bosch plans a wide range of sensors and mechanical equipment for the car, home apparatus, and instruments classifications and is one of only a handful couple of organizations to offer move discovery on their ebike engine frameworks, this is intended to ensure the chain, tape, and derailleur as you ride and change gears and is particularly pertinent and helpful with the high torque Performance Line engines like this

Walk-help has been empowered on this ebike which implies you can get help going it forward in the event that you get a punctured tire or need to bounce off on an especially troublesome or soak segment of trail, simply press the walk mode catch at the base of the presentation and afterward hold the in addition to catch when in any of the four dimensions of help, shift gears to change walk speed


The Performance Line CX is an amazingly noteworthy engine, however it weighs more, makes more clamor, and includes some drag on the off chance that you are taking it to the maximum or are riding with the electric framework off

While the Bosch Purion show board is less powerless, on the grounds that it's little, the screen isn't as simple to peruse as the bigger Bosch Purion and it isn't removable, you get less menus and readouts and there's no Micro USB port worked in for charging (only for diagnostics), however a few shops can enable you to move up to the Intuvia on the off chance that you need it

There is no kickstand here which I was astounded to see, however it has kickstand arrangements and it would appear that they are mounted off the beaten path of the wrench arm which is pleasant as that takes out pedal lock while turning around

There is no incorporated lights here or a Monkey Link setup like a portion of different BULLS bicycles, so that appears as though sort of a botched chance given the quality of the PowerPack 500

No bumper or jug confine supervisors are available, however this was likely because of that standard position of the Bosch PowerPack 500

The charging port for the battery (when mounted to the casing) is near the left wrench arm and could get caught or bowed there… so be additional cautious with the bicycle while charging, don't walk it in reverse in light of the fact that the wrenches will turn

The non-bolting level elastic holds appear somewhat strange given the top notch segments and solace all through the bicycle
