That one is a 98 mine is a 94 basically the sameSure, I looked at some pics. It should be a good candidate for a Bafang BBS02. If you want the security of a front disk brake, you'll have to replace the fork with one that has the tabs. It's probably a a 1" threaded fork. Any 1" fork, threaded or threadless, with tabs is hard to find these days. EIther, there is a surge in DIY conversions of old bikes, or the supply chain just dried up.
I converted a 1992 Trek (rear motor) seven years ago, and 1" threaded suspensions forks were easy to find,. I further had to convert to threadless, but the steerer was long enough to do so. Now those forks are out of stock everywhere, By the way, even I upgraded to a wheel that could take disk brakes, I thought the Trek. upgraded to v-brakes, had plenty of stopping power. I did put a disk brake up front on my BBS02 conversion later, but the main difference is that it's harder to keep in adjustment.
