Summary

  • An efficient, compact, and relatively lightweight, mid-drive electric bike kit that's compatible with 68 mm to 73 mm bottom bracket sizes, works with downtube or rear-rack battery
  • Responsive torque sensing pedal assist as well as throttle mode (choose from half-grip, full-grip, or trigger throttle), get help starting from zero and ride however you want
  • Top speed is adjustable, you can turn off the display backlighting, there's a full-sized USB port built into the display panel and it uses a remote button pad for easier access while steering
  • No shift detection, so it could wear your chain, sprockets, and derailleur out a bit faster if you aren't easing off as you change gears, not as powerful or fast as the specs would suggest
Warning, in some configurations this electric bike kit is classified as a moped or motorcycle and may not be ridden on cycling trails or paths. It may require licensing, insurance and lights when used on public roads.

Written Review

EBR charges a service fee to manufacturers to produce ebike reviews and videos, this began in 2018. It’s the same flat fee for each bike, and it helps us to keep the site going while limiting ad clutter. We appreciate the opportunity to serve you with our opinions and data but respect your right to know that we receive compensation :)

Electric Bike Outfitters sells a range of ebike kits and is a leader in terms of customization and customer support. Most of their kits utilize hub motors which can be mounted either in the front or rear wheel. They offer a range of wheel sizes, silver or black color choice, and different battery capacities. The mid-drive kit is quite different because the only real choice on offer is battery mounting position. You can use a downtube mounted Dolphin style pack or a rear-rack design with integrated LED light. It should work with most wheel sizes but only fits specific bottom bracket widths, 68 mm to 73 mm. I cannot say for sure, but I would guess that it’s only compatible with chain driven bicycles, not belt drives. I say mostly sure, because you can swap the stock 42 tooth chainring with larger sizes to slow the cadence and maximize top speed. What I experienced during this review was a relatively quiet, lightweight ~6 lb, efficient mid-motor. The benefits of a setup like this are reduced unsprung weight (in the case of a bicycle with suspension), easier access to the wheels for maintenance (because you don’t have an extra cable running to one hub and nuts securing a fixed axle), and the ability to empower the motor by shifting gears as you ride. The drawbacks include increased drivetrain wear (on the chain, sprockets, and derailleur), more difficult installation, and the requirement of gear shifting in order to maximize speed or power. For example, if you start from standstill in a high gear, the motor will struggle and climbing will be difficult. I love how compact this thing is, but couldn’t help but feel a little concern about how exposed it might be to rock and log strikes, protruding from the bottom bracket as it does. I appreciate the flexibility of battery mount style and love the display panel, even though it’s unique from every other EBO kit.

I was a little underwhelmed by the power and torque on offer from the Mountaineer at first, because the stats say 350 to 700 watts and up to 80 Newton meters of torque. That’s significantly higher than most of the mainstream electric bike mid-drives that I have reviewed for Bosch, Brose, Yamaha, Shimano, and Bafang. It performed a lot like the lightweight Shimano E6000 mid-motor, which is commonly found on neighborhood and city bikes. Without the anchoring point of high advertised values, I would have approached and received this kit much differently. In practice, it’s an efficient aftermarket mid-drive that performs best when you’re pedaling along actively and has the unique benefit of throttle operation! It uses a torque sensor vs. a more simple on/off type cadence sensor found on some of the older and less sophisticated Bafang BBS01 and BBS02 kits, and that makes it feel smooth and responsive. But for me, it didn’t feel as dynamic or capable as Bosch or Brose, even in the highest level of assist, you cannot really tap into the torque… and it feels pretty weak when starting in a higher gear, as mentioned earlier. One of the other stats that threw me off here was the high RPM cadence matching that Jason (the founder of Electric Bike Outfitters) told me about. It seems like every mid-motor has a pedal speed where it just sort of fades out. The faster you pedal, the less support you might receive from the motor, usually around 100 or 120 RPM. What this means is, you’ll have to switch to a higher gear and pedal slower if you want the motor to contribute effectively. I was initially told that the MXUSE manufactured EBO Mountaineer could hit 4,000 RPM, but Jason was talking about internal drive speed, not pedal strokes… After I published the video, he clarified that the drive unit is rated at 103 RPM, which fits my experience much better and keeps it in line with the Shimano E6000 mid-drive mentioned earlier. Interestingly, even when I pedaled way over 100 RPM, I could still hear the motor whining and activating, I didn’t feel it slowing me down at all, but I just didn’t feel support at those higher levels. So coming back to use cases here… I’d say this motor would be a great fit for active mountain bikers who want to limit weight and convert an existing bike to be electric, or it would be a great fit for neighborhood riders who prefer a mid-motor to a hub motor. Perhaps you have really beautiful rims or want to preserve quick release? Perhaps you want a mid-motor with a throttle? These are all great uses for this kit.

Powering the kit is a 48 volt 11 amp hour battery pack, offering above-average capacity and two mounting configurations. The downtube design is optimal for keeping weight low and centered while reducing frame flex, but it requires a sturdy pair of bottle cage bosses and an open space on your frame that is larger than a standard bottle cage. If you have a step-thru frame, this sort of mounting configuration could expose the battery box to kicks each time you mount and dismount the bike. The ideal configuration would be a diamond high-step frame as shown in the video review. For those with rear rack bosses and space at the rear (meaning that you don’t have oversized fenders or a saddle that is set all the way down and sticking back) the rack battery is a great option. I regularly complain about weight being positioned high up and way towards the back on purpose-built ebikes that use rack mounted batteries, but it’s actually a decent option for doing conversions, because racks attach at four points vs. just two with a mid-battery. The rack battery option frees up your downtube for actual water bottles and gives you the benefit of carrying a trunk bag or panniers in addition to the battery pack! It’s even possible to use this battery design on a hardtail mountain bike, but not advisable. The bolt-on rack looks nice, and comes in two colors (silver or black), but has more potential for shaking around. Regardless of the battery mount you choose, there’s going to be 7+ lbs of weight added to the frame, bolted on using braze-ons (probably) that weren’t designed to hold extreme loads. For this reason, I’d recommend using Loctite Blue super glue and being careful and attentive when riding off-road. Also worth calling out here is the USB charging port built-in to the side of the downtube battery. EBO told me that they de-activated this port purposefully to reduce power draw. It can still be accessed for firmware updates, but the optimal USB charging location is under the display panel… and this location is more accessible too. Whether you charge the battery pack on or off the bike, I suggest storing it in a cool, dry location. Avoid extreme temperatures, try not to drop the pack, and avoid letting the charge drop under 20% because that stresses the Lithium-ion chemistry. Jason recommends recharging every two or three months if you haven’t used the kit, just to avoid hitting those lower fills.

Operating this bike is a two-step process. Both battery packs have hardwired on/off switches built-in (good for keeping them stable during periods of disuse and travel). The downtube pack has a silver circle that you press, and it lights up with blue LED’s, and the rear rack battery has a toggle on/off switch below the light. So, once you’ve charged the battery, clicked the on/off switch, and are ready to ride, you simply press the power button on the display panel itself. This display is large, clear, and highly adjustable. One of my favorite parts about most kits, and certainly the EBO kits, is that they allow you to lower the top speed. This could be useful if you are trying to qualify as Class 1 (pedal assist only, up to 20 mph). The default configuration of the kit is Class 2 (pedal assist and throttle, up to 20 mph), but I think you can actually raise the max speed in the display and go one or two miles per hour beyond 20. There are four levels of assist, Eco, Tour, Speed, and Turbo and I conducted most of the ride testing in Turbo mode to see how zippy the motor would feel, and how much noise it would make. It struggled to climb when I was in higher gears, but did pretty well when I shifted down to the lowest gear. If you’re mounting this kit on a single speed bike, keep in mind that it might start a little slow and struggle with climbing because the torque just isn’t there. Again, looking at this thing side by side with a Bosch, Brose, Yamaha etc. it is physically smaller, but rated at a higher peak torque. My experience was that it’s just not that powerful… but that’s still okay for many situations. Two things I really loved about the display panel were the ability to turn backlighting on and off, and get battery level feedback with six bars vs. just four or five. This makes it more precise and could be the difference between recharging at a half-way point or thinking you have enough juice to get home. Two things I wasn’t so keen on are the fixed nature of the display (you cannot remove it when parking, so it could take more wether exposure or scratches at the rack), and that the battery charger is a bit large and heavy for being a more basic 2 Amp design.

I hope I’m not coming off too strong with this review of the EBO Mountaineer Mid-Drive Kit. It’s one of only a few options for a DIY electric bike system utilizing a mid-motor and offering a throttle. I just want to set expectations accurately. I’m a fit, relatively lightweight ~135 lb rider, and I found it to be fun, but not super zippy. By resetting expectations here and emphasizing the flexibility of how the kit performs, emphasizing the great customer service on offer from Jason and his team, and exploring the benefits and trade-offs of each battery, I hope this helps you to make an informed decision. My favorite kit in the EBO lineup is the 48 Volt Burley hub motor because it balances lightweight nimble handling with zippy power and also has the throttle option. It might not get the same range as this mid-drive kit, if you have a range of gears and shift thoughtfully. Even though you could mash gears with this mid-motor, I don’t think it would stress the drivetrain that much, given the relatively low torque-power output. Big thanks to Jason and his team for partnering with me on this review, It was neat to compare his offering side by side at the company headquarters in Denver, Colorado. I’ll do my best to answer questions in the comments below and welcome you to connect directly with EBO and other owners or enthusiasts in the Electric Bike Outfitters Forums.

Pros:

  • The display panel is large, bright, has adjustable backlighting (on/off), and gives you access to lots of settings like top speed
  • There aren’t many choices for torque sensing mid-motor kits with throttle options, this one is relatively lightweight and compact too
  • Two battery mounting options make this kit extremely versatile, the downtube pack offers the best handling but the rear rack provides additional cargo options and a built-in light
  • Most of hub motors from EBO weigh at least 6 lbs, so this mid-motor is potentially much lighter, it doesn’t come with thicker spokes and the basic rim so your default setup could weigh less and provide better performance for your specific bike (think carbon frame with deep dish rims etc.)
  • You get a remote button pad to control assist, lights, and display readouts, and it can be mounted well within reach of your left grip (so you can change settings without repositioning your hands)
  • EBO has been in business since 2015, they offer a generous 30-day return policy with a one year warranty, and they ship worldwide… I trust them a lot more than some of the generic kits found on Ebay
  • EBO uses nicer parts such as Julet connectors which are water tight and color-coded for easier assembly and repair, you still end up with more wire clutter on a kit vs. purpose built bike, but it’s not as bad since this is a mid-drive vs. wheel-mounted hub
  • Safety is a big focus for me, so I appreciate the more sensitive torque sensor, adjustable top speed settings, and brake lever motor inhibitors
  • If your bike uses hydraulic brakes, EBO does have an optional sensor and magnet unit that can be screwed and glued-on to enable motor inhibiting, but it’s not as elegant or simple as the stock mechanical brake levers
  • The display panel is large, easy to read, full of interesting settings to experiment with (and EBO has a nice manual to help you do so on their website), and it has an integrated USB charging port, though the display cannot be easily removed for protection at bike racks or wet days
  • Even if EBO eventually goes out of business or changes some of their kit hardware, you should still be able to get parts and have your battery case re-packed because they are not software locked and follow an open industry-standard vs. being proprietary, this particular kit is manufactured by MXUS
  • Given that the battery pack weighs ~7.1 lbs, it’s great that there’s a handle built into the top or back (depending on the downtube or rear rack model), so you can carry it more securely, I suggest storing it in a cool dry location and avoiding extreme heat and cold
  • Being able to transform an existing bike into electric with multiple drive modes for around $1.6k seems pretty good to me, there are cheaper kits out there, but most of them don’t offer this level of performance or support and I could see it working very well for a lightweight road bike
  • Before shipping each battery, the team at Electric Bike Outfitters actually drains and refills it to test all of the cells, I was told that they experience a 1% failure rate and by testing like this, it saves you time and hassle as the end consumer
  • With a mid-motor kit, you don’t have to worry about hub spacing or unique forks, it performs well with suspension and reduces unsprung weight compared to a hub

Cons:

  • This mid-drive kit isn’t as sophisticated as some of the purpose-built or upgraded kits I have seen from other companies with shift detection, if you change gears rapidly while pedaling, the chain, sprockets, and derailleur could take increased wear
  • Overall, it isn’t nearly as powerful or capable as the specs would lead you to believe, it compares most closely to the Shimano E6000 motor in my experience, you must shift down your gears to climb effectively and it didn’t offer much support at higher pedal speeds (above 100 RPM)
  • Mid-motor kits tend to be more difficult and time consuming to install because you must remove the bottom bracket, spindle, and crank arms (requiring special tools like a bottom bracket wrench and crankset puller)
  • All of the other EBO kits offer two display choices, but this one only has the stock display (it’s pretty nice, and has a remote button pad for easy operation but stand out more)
  • Your bottom bracket width must be sized between 68 mm to 73 mm or this kit won’t fit, that means it won’t work with most fat bike frames
  • The battery charger is a bit basic, only offering a standard 2 Amp power output, and it’s not super compact or lightweight at ~1.9 lbs… still, it should fit into your backpack or other bags easily for charging on the go
  • Unlike a purpose-built electric bike, kits usually have extra wires that aren’t as hidden or neat looking, the battery mount slide connects to the downtube with two bolts vs. three or some even sturdier custom designs
  • The little rubber cap that protects the charging port on the right side of the downtube battery can sometimes be difficult to seat, it’s a minor annoyance but something worth fiddling with each time to protect this sensitive area from dust and water
  • The display panel has a bit of lag before showing your current ride speed, it uses a spoke magnet and chain stay sensor but it’s just not as refined as many of the purpose built ebikes I have tested
  • This isn’t a big complaint, but the USB charging port on the downtube battery pack has been disabled (to reduce phantom power draw over long periods of disuse), there’s a second USB port on the bottom of the LCD display panel, but sometimes it’s nice to use the battery itself as a backup power source off the bike… it would be nice if that USB worked but could be turned off when the battery was turned off because it has that independent button
  • Turning this bike on and off requires two steps, which adds a bit of time, you first have to click the battery pack itself on and then press the power button on the control pad, just remember to turn it all off before dismounting, transporting, and storing to prevent accidental activation
  • It’s nice that the chainring comes with a sturdy alloy bash guard (outer guide), but it would be nicer to also have an inner guard to keep the chain from bouncing off, this would make it a full chain guide

This motor is a rebranded Tongsheng TSDZ-2, there’s a thread running on Endless-Sphere about this motor which is rebranded by several retailers in different countries. In it’s Austrian guise of the Schachner MM15 this motor was selected by Dutch bike builders to create “V8” models of the Workcycles FR8 mid-tail and KR8 box bikes.

Fantastic feedback Dewey! Thanks for the link and detailed information about the motor. Have you had an opportunity to try it? What do other people think about it?

As a 350W TSDZ2 unit with an 11.5 ah 48v battery, this is a very overpriced unit. Can be individually sourced elsewhere for under 700 dollars. The motor is well under 300 dollars many plqces.

Thanks for the feedback Steve. I asked Jason about his pricing and learned that he insures his stuff, offers that 30 day return policy and 1 year warranty. He has also refined some of the design, connectors, manuals etc. for the hub motor kits and can be reached directly via email or phone. I feel that the higher price is well supported by the customer service, but yeah, it sounds like you could get this thing cheaper elsewhere if you’re willing to forgo that :)

I live on a hill that gets up towards 15% in spots and I have it installed the same motor from another brand on my Yuba Boda Boda, and when the battery is fully charged (up at 56v), it actually does a pretty good job – but as the voltage drops, you really notice the speed dropping.

I find that on a 60lb bike, I’m riding up at about the same speed or a little faster than my partner who is on a Packster that probably comes in at 150lbs of bike+cargo – which definitely agrees with your assessment that it’s not as powerful as the Bosch CX.

Today, the torque sensing stopped working for a few minutes – ultimately, since it’s not the most reliable, I plan eventually to install it on an old mountain bike to be a back-up commuter, using a battery shared with another bike.

Tip for ya’: Its never a good idea to start in high gear on any bike, let alone one with a mid drive motor. You are asking the motor to do way too much, and if you understand torque versus diameter of the sprocket, and gear you are in, then you’d understand the result you are getting. Some Bafangs for instance can deliver 160 Nm of Torque, but that doesn’t mean you want to abuse that, and start out in a high gear, and being able to get going easier, doesn’t mean that is what you should ever do. If you want to stretch the chain, and reek havoc on the entire drive train, by all means feel free to do as you please.

For all ebike riders, and would be purchasers, please use some common sense and realize these motors can add way more power than your own two legs typically can, BUT, also know that your performance of the motor drive and drive train (gears, derailleurs, etc.) is only going to last as long as what you practice in terms of the application. Meaning, please use your gears on the bike, to downshift to lower levels (i.e. 1st gear or 2nd) when hill climbing, and then similarly when on flats or going downhill, put the bike’s gears into the higher speeds (whether you have a 7 speed or 11 speed cassette). Otherwise you are going to make the motor do way more work, drain the battery faster than needed, and reduce the overall longevity of the drive train.

I get a lot of people in my shop who think they are going to just stay in one gear, and move the levels of assist up and down. Well sure you can do that, but don’t expect the motor or drive train to perform as long as it should, and expect to have more maintenance. I would say use common sense, but that is a lot to ask of people who aren’t mechanically inclined, or really understand how gear ratio’s work, and what the impact of torque and speed are when using the typical set up on a bike.

Great feedback Mike, I try to demonstrate different types of riding and encourage shifting (carefully). Your points are valid and it sounds like you’ve seen a lot of different ride styles at your shop. Where are you located, what’s the shop called?
