Let's Get Back to Living
Update on E-assist
Which is best?
- The batteries are the same size but the TSDZ is 52 V vs 48V for Bafang. Mounting ia different Q-TACH but either unit could run either voltage by changing settings
- Range is about the same but generally go a bit faster (22-26 kph) with TSDZ2 as you have to keep presure on pedals to maintain power. tend to coast a little more with the Bafang. The controller software and firmware in the BBSO2B is much different than the cheap controller packages I have on a trishaw with a Bafang hub motor ( I don't like that trishaw e-assist package)
- The TSDZ 2 has a brass reduction gear that is noticeably noisier at slow speeds in lower gears than the BBSO2B. At higher speeds (+20 kph) road noise and "old ears" don't notice it. That noise was initially worse but dropped as the gear "seated in"
- Have a double front (44T and 52T) but never use the 44 as few hills here. I run 55-60 cadence w standard cranks and often run in 6th or 7th on the cassette for better wear life than on the 11 tooth 8th. Most of my miles are on the highway Around town I pooch along at maybe 15 kph. I do not have a shifter on the front chainrings as I rarely shift. It is simpler to take hold of the chain tube and lift it up or down onto the desired chainring
- The BBSO2B seems to have more power and runs cooler than the TSDZ 2 which has the extra packing of thermal paste. It gets warm after a two hour 40 km ride on a summer daybut not "hot" per se. The Bafang never gets more than just warm.
- The newer display that came with the TSDZ 2 is much brighter but it does not have a watt meter like the Bafang.
What Else?
I need:
- Suspension: My old arthritic neck needs some relief and maybe a head rest too. Full suspension or just rear?
- It must fold- quick & easy Tired of hauling a trike over 1000 miles of salt and sand and worrying about the thieves.
- It must take an e-assist system. I am happy with my TSDZ-2 and cost wise it wins hands down. That being said I like to try one of those RR systems
- Rear big wheel to avoid deraileur in the dirt.
I want:
- To try a rear geared hub. I don't need 15 gears. I rarely if ever use the grannies on the cassette. Whats happening with the redesigned 5 speed Sturmey-Archer. Sure like to try one
- An enclosed trike for bad weather. Not a velomobile I cannot get in or out of and that cannot go over a railroad crossing or a pot hole
- What's happening with fairings? Terra Cycle Wind Wrap which I have used won't quite cut it for we poor souls who cannot go south but still need to trike. This picture from Osoyus, B.C, a.k.a. Lotus Land in 2016/17 amply demostrates the problem!

Still Bent
It has been a long two years since my last posts My wife Norma, was diagnosed with multiple myeloma in early 2019. Chemo therapy and isolating to protect her immune system brought remission by late 2019 and we looked forward to expanding our social circle back to normal. Then Covid 19 reared its ugly head so once more we hunkered down to wait it out. Then in mid 2020 the multiple myeloma came back with avengeance. On September 19, 2020, Norma, my Pearl of the Orient peacefully slipped away from me. It has left an awesome pothole in my life.
When I discovered recumbent trikes in late 2015 Norma was my greatest skeptic. "You're going to kill yourself on that stupid thing!" was her often repeated remark. But as she saw my enthusiasm gain, my health improve, and no more of the scrapes and road rash I suffered with my old mountain bike fade into obscurity, she became my biggest Bent on a Budget fan.
"Maybe you should get a better carrier? How about some better lights and a neon yellow hoodie? Why don't you put your trike in the living room, so it's safe?" were offered and never a suggestion anything was too extravagant. No longer had to worry if the Budget might be Bent.
With Norma gone.... but Covid 19 still having me nailed down, my faithful old Rover II still has me wheeling up and down the road. Border closings have removed virtually all the tourist traffic from our #11 Hwy so I am pretty free to roll. Winter is now upon us, but the weather has been unseasonally mild... so far... so here I am on January 13, 2021. just back from a brilliant winter ride with the temperature up to the freezing mark, dazzling sunshine, and no wind. Rover II with it's winter Windwrap Fairing, flashing Cygo lights, and Bafang BBSO2B e-assist is functioning beautifully. But it probably will need some neglected seasonal maintenance soon.
Tomorrow threatens a major storm with wind, freezing rain, and snow. That Arctic Vortex may come rushing in from Siberia and outdoor riding may be over for a month or two. But that's OK. The used Terra Trike Tour II I picked up in 2019 with plans to turn into a velomobile is sitting on a Sprortscrafters Roller in front of the TV. It makes a perfect seat for watching the news and peddling along. The Wahoo sensors I installed show me my cadence and speed, letting me get an hour or two of leg exercise. I tried syncing it with a couple cycle training programs from Zwift and Rouvy but found those programs more suited to racers not old fuddy-duddies like me that are just interested in casually enjoying their ride and the scenery. Something for the winter while Covid has me tied down
But I do have other plans for the spring. I am building up another trike, Perhaps you've heard of the "Lost Recumbemt". It is a leaning trike invented and perfected by Dave Ashenbrenner some 40 years ago. Dave in retirement in Florida decided to revive his dream and is fabricating a few complete units and also frame kits for the AR3 Kazebike. Google it. I will be cannibalizing parts from my Tour II to assmble the unit.
It will be e-assist, and although the Bafang BBSO2B has served me very well, I have ordered a Tongsheng TSDZ2 Unit. This has torque rather than cadence assist and at 500watt rating is 'legal' in Canada while the BBSO2B and 750watt setting bends the rules. I had considered the TSDZ back in 2016 but at that time there were reliability and distribution concerns. So I will have some new experiences in triking.
I also have a couple of mods I made on my Rover II now at well over 35,000km I will detail in coming posts.
How about the theme of Bent on a Budget. I have changed my outlook.

You saved my life. Thank you Rover II
Three years back I could not stand to ride my DF more than a few miles without terrible back and knee pains. So much so I simply wouldn't ride it much. I was overweight, diabetic, and suffered from leg cramps, mainly at night. Fortunately I took a tumble off the old DF and after much fretting and searching purchased a Rover. I knew nothing about recumbent trikes and have kept this blog to recount what I have learned.
Over the last year, nothing much new has happened with my Rover II. Maintenance and repairs have been minimal, but the enjoyment I get from spinning those pedals every day, generally for 50 km has stayed constant. The weight and blood sugar is under control, the back and knees are fine, and the leg cramps... simply gone.
I don't think I have much more to contribute to this blog that is relevant to the title bentonabudget. I've pretty much blown the budget part.... according to my wife. But I think the investment was very worthwhile, and has paid me substantial dividends. No regrets
A quick summary of the best additions I have made to the Rover as I went along.
- SPD pedals and shoes
- Cygo Hotshot Rear light
- Mirracycle Mirrors
- 24" Rear Wheel, Big Ben Tires
- 3 speed front ring (before E-assist)
- E-Assist Bafang BBS02B w 13.5ah 48v Battery
So that is it. Bentonabudget probably will not have any new posts. I'll leave this blogspot up in case some momentous thing comes up, but more reasonably as a reference should someone care to look. So far this blog has been visited 5578 times. To all you who looked hope you found it worth it.
I am keeping Rover II and expect to ride it for many more years. It goes as fast and as far as I want, but I have a new project in mind... a velomobile.... of some sort. I don't need or want to go any faster, but I do need a way to be comfortable in those sub-zero Canadian winters. Florida has provided that option so far, but may not be a future option. My Windwrap faring does a decent job to just below freezing, but below 10F it simply isn't good enough.... that leaves about 4 months Dec thru March unrideable in my neck of the woods.
So what velomobile? A dedicated one? A kit? A trike conversion? How about a coroplast? Something to look forward to.

Can you stop?
I removed the unit and the actuator arm was 'sticky and crunchy'. I pulled it apart as far as I could get it and prepared to order a new set of Avid BB7s. My first search on Amazon for same came up with a 'good as Avid BB7 replacement brake set' only 28 bucks delivered for both complete w new rotors. A few dozen positive reviews and one very negative. What the heck $28 vs $135 for the genuine Avid BB7s. What could possibly go wrong.
![]() |
The new AfterPartz disk rotor and caliper installed (and ready to fail) and the wheel back in place |
The delivery was prompt. The contents of the box looked good. But there was no instructions and no link to same to be found. No problem I plunged on ahead. A disk brake set is a disk brake set, right? I looked at the Avid sight for BB7s and BB5s and followed along. Put on the rotor... no problem. The hardware for the caliper mount was identical to what the Alhonga used... seems standard on all disks and most kits come with two different sets of mounts depending on configuration. Mounted up, adjusted, and hooked up the cable.
Time to test, Spin the wheel, apply the brake and 'click!' The actuator arm moves forward and tension applied to the disk is lost. Spent a half day trying to figure out why. Gave up in disgust and installed the other caliper. Seemed okay, took for ride next morning after 5km, 'Click!' No pressure on disk.. Disconnected cable, fiddled with actuator arm, seemed to reset. Reconnected cable readjusted and resumed ride. After 45 km, pulling into the elevator lobby at the condo, 'Click!' No brakes.
There followed a whole series of emails with the supplier, Amazon and vendor AfterPartz. Someplace in there I gave up and ordered a set of Avid BB7s again from Amazon. They arrived promptly and I installed per their excellent series of YouTube videos ( pretty much the same procedure as used on the AfterPartz. The Avid BB7s worked flawlessly. Beautifully modulated and effective.
AfterPartz had offered several times to send me a replacement set, a discount, or a refund (No need to return the original set). I accept the refund.
Curiosity had to be satisfied. I took the AfterPartz units apart several time to see if I could determine why they failed to work. It is easy to disassembleThe following points were noted:
- There were traces of 'tramp' material inside the body of the caliper, that was probably preventing the ridge on the inside ramp from mating firmly with the notch in the caliper body. This ridge/notch keeps the inside ramp from rotating. Rotation would cause the bearings in the actuation ramp to slip back into neutral position.
- If the actuator arm was applied too fully without a disc inserted between the pads, it could again cause the ridge in the bottom ramp to slip out of the notch in the body causing slippage.
- There is no lubricant inside the caliper mechanism. What does that portend to service life?
- There are no thrust bearings in the mechanism.

Fall Maintenance

King Pin Greased and ready for insertion |

New and used bushing. Which is which? |
Thought I might need to replace the steering bushings now around 12,000 km, so ordered a new set and waited for a reamer to arrive in case the new ones were too tight as reported in the forums recently. Loosing track of my mileage. But hardly ever miss a day and then do 40-50 km
I dropped the kingpins out of the frame and tapped out the bushings with a punch and hammer one side at a time. Checked for wear visually and with my calipers. There is no indication of wear on any of the bushings. Can't see any difference between the old ones and the new set so cleaned, greased, reassembled, and adjusted. Messy but was cheap and easy. This is the 3rd time I've completed this lubing procedure.
Was really surprised there was no significant wear. Have never really had a problem with steering and quite pleased at Rover II's service
Greasing the final drive in the Bafang BBSO2 was something I had not yet done. I have not taken anything apart on it. since it was installed. The unit runs very quiet still, and I don't really push it very hard, but wanted to take a look inside. There are two sets of drive gears to service. The one on the right side has two steel gears and needs to have the grease replaced before it migrates through the central seal and contaminates to grease in the left side. The plastic gear in the left side is more difficult to open and service, and the stock grease in the right side, can deteriorate that plastic gear. Eventually I will have to service the left side but will try to leave that until next year. (Early Bafang units often were shipped lacking grease) A new adventure.
The procedure was as follows:
