This bike came together slowly. I bought a TongSheng TSDZ2 kit in 2019. Never found a bike for it. In 2021, I picked up a 1980's all steel Raleigh Mixtee at a garage sale, and it sat outdoors for 18 months, Last September seemed like it was time to put the two together.

It's the 500W 48V model motor. I've changed the settings in the motor from 12A to 15A max. All of my other bikes are 20A, so the TSDZ2 is prettypuny in comparison. However, it's down around 40 pounds, so I can pedal it all day w.o power on flat country.

I changed out the steel rims for alloy rims. A six speed freewheel replaced the orighinal 5 speed. Found a junker Shjimano Tournery derailleur in my parts bin along with a quickfire trigger shifter. New KMC chain. Also had an old allow quill and bars to replace the original steel ones.

The battery is a 26 cell 48V7AH pack that I made out of Sanyo GA cells, and stuck inside a metal water bottle. I have ridden over 40 miles on it. It's 300 watt-hours (measured) and the bike uses 5WH.mile, so I believe 50 miles is possible. That;s because the TSDZ2 makes me do most of the work. I moved the battery to the lower bar, and use three Velo-Orange clips and a standard water bottle bracket to hold it.

For the last few days, I've been hanging out in the garage with a laptop and programming cable attached to the bike trying to loosen up the firmware so I can go faster and burn up the motor. It seems promising. All I want is little more assist on the pedals. Ah, it's a task for a nerd. I thought I bricked the motor twice, but it's still running.

Forty five years ago, we had a red one like this, It brings back the memories.

Nice work! I like that you seemed to enjoy the project and you repurposed an old bike for it.

I have to say I love this ebike conversion to 1500W hub with a 52V 17.5Ah battery.

It's immense fun out in the nice weather...need to think about mudguards now but don't want to take the face of the bike as I really like how it's currently looks (even with the black forks) , the hub/battery is bit of a give away though if you're looking...

BEFORE

Old Halfords MTB (could be 20 yrs old...), think it was my sister's, rescued form elderly parents shed.




DURING

Cold setting frame before shot blasting, respray and build.




AFTER

Since these pics were taken I've rebuilt drive train and put on new derailleur/shifter, currently designing my own torque arm for drive side.

New brakes, new black front fork after respray (grrr...as I bent original forks in a crash when rear axle spun out on test drive)

Also have tidied up the cables at front in to a nice bag.

A Magicycle for my entire family!

I'm definitely "sold" on the Magicycle brand. After my third cruiser arrived on my doorstep this week, I'm glad to say that excellent quality and customer service are still in place at Magicycle. Only 4 days from order to delivery! Now I need one more to have enough for all my family to ride together. I might even consider their new folding e-bike.
It's getting cold an wet here now, but I'm still riding :-) These fat tires give very nice traction in a variety of winter conditions! Magicyle always installs brand name components on their e-bikes, so I'm very comfortable about riding long-distance, even in winter.

It seems I am not yet allowed to post photos or links, but if you want to see them, just let me know.

Wow -- not exactly friendly

I'm not allowed to like my bikes and eventually qualify to post a photo? I believe this is the "Post your e.bike pictures here" area. Have a great weekend!

Wow, 1500 watts-- the thing must really fly! I had one with 1000 watts and it was scary sometimes.
