I am faced four critical issues and I did contact Customer Service (Suzan) before I leave a critical rating, unfortunately no success. 1- The bike I received was not new, mainly because the display worked without me needing to use the password. I didn't do anything and it was already working... and also because there were signs of assembly tools on the item to be assembled, such as the front wheel 2- Battery Range is ridiculous, to fair away of the seller specification. I just used pedal assistance , I used the bike 3 charges to really take care average of Battery range and I was never able to reach 19miles of range using pedal assistance (P2/P3) .. this number should be 50-68miles .. all in all, something is wrong with this battery as it is capable just 30% of range specification. *remarks: my weight is 198lbs. 3- The bike makes a lot of noise on the pedal, when I'm standing still, just when I put my foot on it to start the movement, it makes that squeaking noise... and when I actually start pedaling, the noise is very loud and unbearable... it stops. that there is a lack of lubrication in everything or there is something wrong. 4- The gears are not adjusted, when I do an up or down shift, the gears don't engage correctly, it keeps making that noise that it hasn't engaged and when I pedal hard, it jumps gears (pure Gear jump out) and makes a loud noise. This happens mainly in gears 3-7... The gears have not been adjusted. Good points Bike has good and strong aluminum frame.

I wanted to give some time to truly test the R5 Pro before giving it a quality review. This is long but hopefully will alleviate any hesitation on purchasing. Over the past 6 months my friends and I have ordered a total of 7 of the R5 pros and I have personally put over 700 miles on mine split between road, dirt trail, and truly offroad terrain. Our e-bike gang consists of a wide range of riders 21-55 years old, 100lb to 250lb, 5’4-6’2 in height and of various athletic abilities. I have written this with all perspectives in consideration. Pros: - Long range/Battery life – As many reviews before me have noted the range is great. This is dependent on a number of factors. Terrain, Power assist settings, shifting gears, maintaining and cleaning the bike chain and cassette, and rider weight. Our average ride is around 30 miles but we have taken them on rides of up to 70 miles without an issue. On longer rides we do keep it in PAS1 and have returned with 2 or 5 bars on the battery. I am confident we could get 80-90 miles if we tried. That said it is tempting to dial the PAS up which takes away from the battery life. Do not buy this bike thinking you will go 30mph for 90 miles on all battery. Also note that battery anxiety is a real thing so until you are comfortable with the range do not plan long rides. Take it slow and get used to it first. - Off-Road Performance/Power – Breaking this into two parts off-road and road. I have ridden the R5 pro on some pretty rough terrain with some steep hills, ruts and logs in the path etc. In this kind of terrain the R5 pro handles it like a champ. It is not like riding my hardtail Trek bikes at all. I can reasonably maintain 8-10mph safely. The challenges are the bike is heavy (72lbs) and top heavy with the high battery placement. So there are times that it can drag you over if you are not careful. I am 6’2 220 and I have managed to buck off once but my wife is not comfortable riding the trails due to this. Also note your battery life will suffer on offroad due to the increased load. - Road Performance/Power – This is excellent. We easily go long distances and can go up to 32 MPH when diving in hard. When riding on PAS1 we average about 12mph on road and PAS5 easily reaches 25 without peddling. Note again PAS5 will kill the battery. On PAS5 I would assume a range of only 15-20 miles vs riding in PAS1 has been proven to us to go 70 miles easily. Usually we do a combination. - Quality/Value/Assembly – Across the 7 bikes I have built the longest part is opening the box and cutting the 100s of zip ties to protect these things. I am able to assemble them in around 15-20 mins once everything is opened and laid out. That said the instructions are terrible, you kind of need a gut feel on some of the less obvious parts. Also there has been some lite variation between the bikes. Having ordered and assembled so many I noticed the breaks, front fork, fenders, latches and other have changed. Nothing out of the ordinary as they improve the bikes but this has led to some variation in the builds. IMPORTANT tighten all the bolts not just the ones you expect to. Most clicks and noises on bikes are related to loose bolts. On 2 of the bikes we had an annoying click that took awhile to diagnose. Turned out it was the pedal arm was not tight enough. Not a quality issue. - Customer Service – Across all the bikes we have only had one issue and it was minor and customer support was great - Size/comfort/features – These are big bikes and demand a presence. That said my wife has no issue controlling the bike on smoother terrain. The twist throttle is a godsend often and utilizing it will vastly improve your experience. The headlight is bright and we have no issues riding after dark, although it is not preferable it happens. The horn is loud enough that you can make people with headphones on jump so does the job haha. Comfort wise I have a lot of experience on bikes and these are not bad. I mean obviously you need to build up some butt tolerance but that’s normal. The Seat is better than most although it does have a button for the light that has poor placement. The only performance upgrade not included in the bike as you may notice in many reviews is the pedals. While they are not bad they can be slick with wet feet. I changed mine out to some gnarly ones and love them. We also put bags on the rear rack to hold bike chains and I always carry the tool kit that came with the bike. - Documentation/resources – There is a Burchda Facebook group which has a reasonably good community. The YouTube Videos can be a bit misleading in my opinion due to changes in the bike. The App does not work with most bikes but is really not needed the settings are all adjustable on the d-pad but I caution you on this as the flexibility in there could break things if you are not careful. All this said the reason we have so many is almost every time someone new rides one they get excited and start looking into e-bikes. Everyone loves these things and we clearly found a winner. Several more of my friends intend to buy at least 3 more over the next few months leading to 10+ in our crew. So after all this I highly recommend these even compared directly to some very clear competition that may look better but are not.

Nice bike but absolutely no chance of getting battery, charger or other Burchda specific components other than thru the China sourced distributor. I know, I've tried almost 1 year later for a part that is not attainable elsewhere, and they did not come thru. After several emails back and forth I have finally asked for a refund on the charger, who knows if I'll get it. EXTREMLY DISAPPOINTED! I will buy my next off road Ebike American sourced. Sold through Damson, even their website has an undeliverable customer service email.

I don't have much experience with ebike or bikes in general. But let me say this, I am 100% satisfied with my purchase. I have run into issues mostly with shipping with FedEx, but it is not in seller's control. Seller acutally was kind and understanding enough to refund half of my shipping money. The bike comes well padded, so it's unlikely to get broken pieces. I have so far done about 40 miles on this bike and it works amazing. I am currently running into issue of very mild mechanical noise, but it seems to be improving, the more I ride. Again, the seller has good attitude and offered me all the support I would expect with this issue. They have offered me to cover in case any repair is required. The battery lasts for a long time regardless of the weight of the bike and size of motor. The charger works fast enough. I would say it takes 4-6 for a full charge. The bike has good enough power and speed as well. It is fun to ride slow or fast. The suspension is very comfortable. Seat Quality is good, but little extra padding is worth getting for additional comfort if needed. Headlight and tail light at night is impressive and seems to cause no issue ride your bike at night. Overall, there are $6000 ebikes available to buy, but this bike is good enough for the price point if you are just looking to get a Quality ebike for the price range.

I’m 18 miles into this bike and I love it so far. Out of the box, it was impressively sturdy. 30-45 minutes of uncomplicated assembly and it was ready to go. I’m using it for small neighborhood rides, but mainly as a commute to work (12mi one-way). Overall I’m very impressed; will update review later this year. DON’T KNOWs: battery life (seems good so far) PROs: durable, easy to fold, bright lights, comfortable seat, hydraulic brakes work great, easy to assemble, fast (28mph+ on straightaway) CONs: hefty (I knew this before purchase, but it’s notable to mention), had to ‘shape’ the fender to not rub against tire, cargo rack was not in stock at time of purchase (however, seller did contact me for notification of this), battery charger connection is different than most bikes (and extra chargers not sold separately; I wanted one to have at work and home).

No fluff. Just the truth. I was asked to remove my first posting stating that the bike was detective. I bought this bike cause it looked beefy and thought the battery would get me a few miles of travel. Well, the bike has disappointed to say the least. The pedal keeps coming off (the co sent me a new crank since it is defective). But complicated to replace without paying a bike shop. The co. send me an assitiinal battery cause the battery only lasts a few miles. It sucks that the battery is loaded from the underside of the frame. There are several concerns with this bike, so I urge you to look elsewhere. The customer service peeps are nice, but the bike is not as expected. Now I'm stuck with it.

I've just gotten this, I've only put 12+ miles on it and that doesn't seem to register on the battery yet. I've been using lots of motor, levels 3-5, for all that riding. I'm happy with the power & speed. I don't love the motor control: this is my first ebike so maybe I'm being picky. The power levels, 0-5, really equate to the top speed (top pure-motor is around 23 mph). Whether that's triggered by pedaling, or twisting the throttle, it turns on pretty abruptly and plows forward. So there is no nuanced speed control: if I want to slow down for a sharp corner, I either brake (thereby turning off the motor), and/or I switch to a lower power level, which is inconveniently done with the left thumb. That all makes it finicky in city traffic, to me. I wish the throttle worked like a motorcycle, variable speed. That said, it's all new to me, and I expect to get better at it. There might even be settings or something I can change. Note that if I go into that corner having braked, but not having turned down the speed, and then pedal little, it will snap back on which can feel quite dangerous in a corner. Again, this may be user error, maybe there's a better way to do corners/slowdowns. The big downside that I hadn't accounted for is how wide the frame hinge/lock mechanism is. The first time I rode it I smashed my knees into it whenever I pedaled, which was excruciating. I put some padding (cardboard) over the joint, and the problem went away: no sharp metal edges, and my knees sort of gently slid against it. I'm going to figure out a better strategy, probably just prettier padding. I expect to be peddling most of the time, so that needs to work for me. I briefly thought about returning it if I couldn't work around that, but 1) that's the cost of foldability, and 2) I think it's really important to be foldable, for me. Many people could probably live with 20" wheels, which would move that joint much lower depending on the design. I really like the 26" wheels, though frankly the bike feels gargantuan. Which is fine. The major reason I got this is to commute and run errands. I wish it came with integral wheel locks and a key on/off switch, but none of them do as far as I can tell. I think I'll get 1-2 disk brake locks for the wheels. I may try to rig some way to disable the power to it. I like that the battery is locked in. It is heavy, but I can carry it briefly: it is very unwieldy, especially when folded. There's a welded-on bracket underneath the that protects that sprocket, which reduces the clearance by around 2" I think. It's just the size to get in the way pushing it up or down stairs, which is really tedious. I might cut it off. That said, if you misjudged and bottomed the bike out on it's sprocket, something would break, and it could be your bottom bracket there's so much weight involved, so I appreciate the sentiment. It went together very easily. The headlight was a pain, but that's mostly b/c I mixed up the bolts. It's a somewhat finicky bracket design, and way larger than it needs to be, but bright enough I think and solidly mounted. The rear light seems nice and bright too. The seat light is powered by a little battery, and it's very easy to trigger when you grab the seat, so I expect to run that battery out in no time. I may add more lights, but this is a very good start. When bolting on the rack (it comes 1/2 installed, you just have to swing it down and install two bolts), take some large pliers or a crescent wrench and gently twist the tabs a bit before you install the bolts. It's quite easy to get good alignment with the frame, but those tabs arrive straight instead of angled (with the frame), and you wouldn't want to install it without better alignment between the frame and those tabs. If it weren't so easy to fix, I would subtract 1/4 star for that. It took 30 seconds. Just do it. The rack is amazing. I mean, I haven't actually used it, but it seems insanely solid. I had expected to swap out the seat b/c I'm very picky, but I'm enjoying it's comfy plushness, so maybe not. So far, I love it. My only durable complaint is the lack of nuanced real-time speed control. As I learn more about that, maybe I'll get used to it, or maybe I'll try to figure out how to install a different controller, which would be a huge task. I will try to rig some disable switch: without removing the battery, I don't think there's anything stopping someone from coming up, turning it on, and spinning up the rear wheel, which would not go well if there were disc brake locks installed. So yeah. It's a great bike for the price. Good workmanship. The horn is probably good for traffic, but too loud for pedestrians: I'll get a little ding-bell so I don't scare people out of their pants. Oh, the brakes in combo with the big tires are powerful. It feels like I can stop as fast as I dare. It's a g-force thing. I expect to add panniers for grocery shopping (looking at these: https://www.amazon.com/gp/product/B0C7FS24PJ/ref=ewc_pr_img_2?smid=A2YNSTVTK080NE&psc=1) and I already ordered puncture-resistant tire liners: the tires are very soft and flexible, and I worry that they wouldn't last through all the crap I ride through and over in the city. I'll probably put on heavier tires when I replace them, but I'll probably ride these until they're spent. They are very sticky/conformable, so fantastic incredible traction. The shocks, which I don't yet know how to adjust, are cushy. It takes speed bumps better than my car. The combo of the big tires and shocks makes this a really great city bike: no matter what road situation I might get forced into (potholes, curbs...), I stand a better chance of surviving surprises on this than any bike I've ever ridden. That frees up road-surface-attention for situational awareness. This is part of why I got 26" wheels, less susceptibility to small-object encounters, and I immediately noticed that I spend less energy trying to see every detail of the road ahead. If I smack into an unseen speed bump, the jolt won't be fun but I will probably keep on trucking just fine. I'll probably add more later. So far so good.

Came mostly set up. My part was easy. Love this bike. Had to replace the brake pads after the end of a season. Actual ebike pads may be better than bike pads as the bike is heavy and I live in an area steep with hills

I really enjoyed driving around the city. It handles the sidewalks to curves great. go off-road. Love it lots of power once you kick front wheel inn

So far i am very impressed with this Ebike. I have pushed it to its limits and found that it performs very well. The distance so far has been very good in a single charge. I found i needed to keep battery inside as i live in Canada and it gets cold. 100% recommend!! Also customer service so far has been very good!

This bike is quite heavy, weighing nearly 100 lbs. It performs very well and is comfortable for me at 6' 4". I can easily achieve 160 km on a single charge, primarily on level ground. As a mechanic with around 40 years of experience, I found that it took over 1.5 hours to assemble. It is quite awkward to put together alone.

I'm a heavier guy so I thought id give this bike a try as it says it has a high weight rating. The bike is built solid has lots of powder and im very impressed with the battery life so far, would recommend

I received the bike within the timelines advised and so could not be happier, the build itself was straight forward enough, plenty of videos online for the R5 just in case you have issues (front light was my only stumbling block). The quality is very good, it is certainly on the heavier side but not too much of an issue and handles well. I had one issue and so a note to all when assembling, the rear stowage rack assembly is very strong, it is being held by some small bolts not sure the size maybe M3 or 4, you really need to tighten both in unison, I had both in and one partial whilst tightening and it popped the other one out, which meant it stripped the threads in the frame not the bolt and now I cannot secure it properly! Not sure what to do at this time, likely need to re-thread with tap set and put larger bolt in! Other than that I personally think this bike is very good and my son, who it was a gift for is extremely happy.
