    Firmware, throttle and other questions on TSDZ2

    So, basically RTFT? That was very helpful ... In case other lost souls are wondering about the same questions I had. The throttle can be incorporated, but requires some soldering into the integrated motor controller (not the display) to make the connectors available. The discussion is around...

    Firmware, throttle and other questions on TSDZ2

    I know there is a giant thread ... and I have read large parts of it, but I am still unclear about a few things. I bought a TSDZ2 (48V version) last year and for various reasons I only got around to setting it up recently. It is mounted on a commuter bike, with a 52V battery using a buck...

    Road Bike or Comfort Bike?

    It sounds like you really enjoy riding your current commuter, so I would not hesitate to use that for your conversion. I would strongly recommend the bb02. I have the BBSHD and have moved it around do between a commuter similar to yours and a cargo bike. One of the nice features is that if the...

    Middrive vs. rear hub for my first e-bike

    My local topography is similar to yours, I live 2/3rds up a fairly steep hill, but the rest of my usual routes are reasonably flat. I use my long tail cargo bike to haul kids and groceries. The bike (radwagon) started life as a pre-built 750W DD rear hub, but I found it inadequate on hills. The...

    cyclocross ebike project

    Just to throw some more experiences in to the mix. I have a BBSHD (48V) kit which I have mounted on 2 very different bikes and used for my 6 mile (each way) commute. My commute has one extremely steep hill and then around 15 lights/stop signs. The first time around I mounted the BBSHD on a...

    Hub motor vs BBSHD for hill climbing fat guy

    I ride a cargo bike (radwagon), so it is very heavy by itself and I live in the middle of a very steep hill. My bike initially came with a DD rear hub motor and although it was mostly fine. It was not able to get the bike+rider and two small kids up my hill even with full crazy pedal input...

    Looking for some guidedence, commuter bike & motor

    Hi, I am not very experienced, but I recently installed a Bafang BBSHD on a very similar bike than the one you bought. It was pretty straightforward and I thought the performance was great. At my home we dubbed the thing the "pocket rocket" because that motor on a light bike really gives you...

    Help rebalancing my bike collection

    In case anyone is curious about the radwagon with a BBSHD. Here is the current state of the bike. All of the functional bits and pieces are there, but I need to clean things up a bit in the handlebar and connect the some of the auxiliary bits and pieces like motor cutout, speed sensor, etc...

    Help rebalancing my bike collection

    That sounds way worse than mine. I could ride my bike on a flat with any gear combination. It is just that the drag from the motor was very noticeable and it bothered me because I like to ride without assist when I can, and of course there was the fact that I could not get up the hill with the 2...

    Help rebalancing my bike collection

    Yes! I installed it last week and yesterday was the first true test on the road with cargo. I don't have pictures on hand but I will describe roughly what I did. I had a stock radwagon, which is a long tail cargo bike that comes with a read DD motor of 750W. 1. I took out the bottom bracket...

    Help rebalancing my bike collection

    Thanks for all the feedback. Now some more detailed questions. As a reminder, I have a geared motor that used to run on an older Schwimm electric bike at 24 V. The old battery is dead; I want to transfer this motor to my commuter (a Marin Fairfax) and I want to reuse an extra (virtually unused...

    That would be fun ... if I had more time to play with things ... and so much for simplifying my setups :)

    Help rebalancing my bike collection

    It is certainly looking that way. So no, onwards to find a reasonable sine wave controller and figure out how to hook it up! On my radwagon front: I have mounted the BBSHD (very straightforward) and yesterday found a replacement wheel for the rear hub. I am keeping the 7 speed on the back so...

    Help rebalancing my bike collection

    Hmmmm, that seems rather steep, although I do like how compact it is. I do care about ringing, I assume that you are asking because of square wave vs sine wave controllers. I am definitively willing to pay a little more for a smoother functioning controlled, but hopefully not quite that much...

    Help rebalancing my bike collection

    Thanks for the reassurance and the tips! This small geared motor would go in my commute bike that is meant to "train" me to be a better cyclist, so I really don't use the motor much. With the BBSHD I would engage it for maybe a total of 5 minutes on a 30 minute commute, mostly for my initial...

    Help rebalancing my bike collection

    No, I have not tried the 700c on the radwagon for a couple of reasons. The first is that I am not sure the wheel is sturdy enough for the use I want to give the radwagon. Also, the 700c wheel is for rim brakes and the radwagon uses disk, and finally, the added (or perceived!) complexity. I just...

    Help rebalancing my bike collection

    Thanks all for the responses. Everybody agrees on the carbon fork not being a good candidate. I guess I knew that ... but was hoping someone had a magical suggestion that let me use it instead of going out and buying a steel fork for this. OK, back to the more practical aspects of this ... I...

    Help rebalancing my bike collection

    I blame all of you in this forum for my descent into electric bike madness. So, here is the deal. I wanted an electric cargo bike for commuting and for carrying my kids to daycare. After much soul searching and some realistic evaluations of my available time for tinkering, I bought a radwagon...

    Radwagon Cargo bike

    I have had a radwagon for a few months now. I am generally very satisfied with the bike. I did not have any problems with the gears, I regularly shift through the whole range (I try to pedal as much as I can in my commute) and I live in the middle of an extremely steep hill (+20%). Even in the...

    Measuring effort on an e-bike

    Agreed, that there are other ways of getting a ballpark idea of effort. As I said, I like the idea of a direct measurement. The CA 3 with the thun seems like it will be perfect and fun to set up... Getting torque based PAS is just a very nice extra. I don't think I would ever use the variable...

    Measuring effort on an e-bike

    Hmmm, this project seems to be getting more interesting by the moment :). From what you are saying, with the same changes I would do to get "human power" I can also upgrade to torque based pedal assist, which was always in my e-bike wishlist but I eventually gave up on when I got a pre-built...

    Measuring effort on an e-bike

    Lots of interesting suggestions. Thanks guys! Let me address some of them and clarify a little further. True, I was not very explicit. I have a radwagon e-bike, which is an off the shelf longtail cargo bike with a rear hub motor. My price range is not really fixed. This is more of a fun project...

    Measuring effort on an e-bike

    Hi there, I would like to track my level of effort in my commute with my e-bike (rear hub) but I am not completely sure how to go about it. I am thinking something like a pedal based power meter. Has anyone tried? Any opinions or recommendations? Thanks!

    Overwhelmed: Advice on Mundo + mid-drive combination

    These two statements are making me lean towards the Bafang again: Man, I thought this was going to be a nice little project to put together for my big birthday, but it sure is looking complicated ... and I am only in the research stage! So, it looks like I can get a Bafang BBSHD kit and...

    Overwhelmed: Advice on Mundo + mid-drive combination

    Lots of good information in the responses: Okay, I get it now. With the usual mid-drive kits it is not clear where to set a torque sensor so that your input and the motor input are not mixed up. I think this makes it clear to me that I am not going to do a torque sensor in a mid-drive in the...
